Hello, I am writing some code where i want user to enter the date in format(dd/mm/yyyy). how can i cross check if user has entered the date in correct format? second question, how can i split the date and store it in different variables? Example: let say user entered 26/05/2013 values should be stored like this in different variables int dd = 26 int mm = 05 int yyyy = 2013
Thank you

So presumably you have some code to show us? What have you attempted so far? Otherwise it seems that you are just asking someone to provide the entire solution for you.

DateFormat format = new SimpleDateFormat("dd-MM-yyyy"); format.parse(date1); System.out.println("Date " + date1 + " is not valid according to " + ((SimpleDateFormat) format).toPattern() + " pattern.");
the above code always throws an exception "not valid according to the format", whatever be the date. i need the tip/hint for the second question not the entire code />

The date format "dd-MM-yyyy" is not the same as the date format given in your first post.
Does it throw an exception, or does it just display the message that you have told it to display?
This line:
format.parse(date1);
does nothing as you do not assign the result to anything.

With $671,400, you could buy roughly 2,040.7 base-model iPad minis before taxes. One unnamed buyer, however, just laid that amount out for a single Apple 1 from 1976. Auctioned through a Germany-based Sotheby's Uwe Breker, The New York Times Bits blog notes the price beats out the firm's $640K record from another unit last November. Interestingly, the seller refurbished this latest Apple 1 to working condition, after paying only $40K for it privately. While it doesn't seem to have the original enclosure, we'd be remiss not to mention that the seller also had Steve Wozniak grace the motherboard with his signature. You'll find more info at the source, while we wrap our heads around how this makes last summer's Sotheby's auction price of $374.5K look like a relative steal.
Update: We initially reported that the auction was held through Sotheby's, when it was actually done by Uwe Breker. We've corrected this in this post.
PITTSBURGH (AP) ? Boston or the New York Rangers? To be honest, Ottawa's Daniel Alfredsson doesn't think it matters who the Pittsburgh Penguins face in the Eastern Conference finals.
At the moment, Alfredsson believes the Penguins are a cut above.
"I think they would be the favorite to play either of those two teams," Alfredsson said. "They have skill, speed, they're well-coached and a lot of experience as well. So they're going to be a tough team to beat."
Certainly too tough for the Senators.
James Neal recorded his first playoff hat trick and Pittsburgh reached the conference finals for the first time since 2009 with a 6-2 dismantling of Ottawa on Friday night, winning the best-of-seven series in five games.
The Penguins improved to 8-3 in the postseason. Eight more wins and they'll hoist the Cup for the fourth time in franchise history.
"The further you go, the tougher it gets," Penguins defenseman Doug Murray said. "Every player starts smelling the end result."
Certainly it's wafting through the Pittsburgh dressing room after the Penguins dominated one of the NHL's best defensive teams, rolling up 22 goals in five games, including 12 in the last five periods.
"We got to our game a lot," Pittsburgh captain Sidney Crosby said. "The depth we showed, different guys chipping in. The whole way through we didn't have many lulls where we lost momentum at any point."
Kris Letang, Evgeni Malkin and Brenden Morrow also scored, and Tomas Vokoun made 29 saves as top-seeded Pittsburgh ended Ottawa's season for the third time in five years.
Milan Michalek and Kyle Turris scored for the Senators. Craig Anderson stopped 27 shots, but Ottawa simply couldn't keep up.
"I hope (the Penguins) don't bill us for the clinic," Senators coach Paul MacLean said. "But they really showed the step you have to take to continue to play in the Stanley Cup Playoffs."
The Penguins expected desperation from a team trying to extend its season for at least another 48 hours. Instead, the Senators offered only resignation.
Outskated, outshot and outworked from the opening faceoff, Ottawa put up little resistance.
"We gave them too many freebie chances and you're not going to beat a team like that when they get as many chances as they had," Senators forward Jason Spezza said.
The series win was the seventh for the Penguins under coach Dan Bylsma but the first deciding victory to come on home ice. Pittsburgh had gone 0-6 at home in potential series enders, something Bylsma's players insisted was an anomaly.
Pittsburgh made sure a trip to Canada for Game 6 wouldn't be necessary, turning Alfredsson into a prophet of sorts. The NHL's longest-tenured captain said the Senators "probably" couldn't rally to win the series after a 7-3 home loss in Game 4 on Wednesday night.
Alfredsson clarified his remarks Thursday, insisting his team still had a chance, but it didn't take long Friday night for slim to turn into none.
"We weren't able to slow them down," Alfredsson said.
Sluggish from the opening faceoff, the Senators slogged through the game's first 10 minutes, long enough for Morrow to pay immediate dividends in his return to the lineup.
The veteran forward was scratched from Game 4 in favor of rookie Beau Bennett but appeared re-energized after the night off. He got his second goal of the playoffs 6:25 into the first period, scoring the type of goal the Penguins expected when they acquired the 34-year-old from Dallas just before the trade deadline.
Pittsburgh's Matt Cooke beat a Senator to a loose puck along the halfboards then zipped a cross-ice pass to defenseman Mark Eaton. Morrow skated to the net and lifted his stick up to draw Eaton's attention. Eaton patiently waited for Morrow to get in front of the crease before throwing a puck toward the net that deflected off Morrow's skate and into the net.
The goal was held up on review and the Senators found themselves in familiar position: trailing.
Ottawa came into the game having led for just 17 minutes in regulation during the entire series, all in Game 4 before Pittsburgh buried the Senators with a four-goal outburst in the third period.
This time, the deluge came a little earlier.
Neal scored for the third time in two games when he poked in an idle rebound on the power play to put Pittsburgh up 2-0 7:38 into the second period. Letang followed with a wrist shot over Anderson's glove at the end of a 3-on-2 break to make it 3-0.
Michalek briefly made it competitive with a beautiful deke around Vokoun to pull the Senators to 3-1 with 3:48 left in the second but Malkin scored his fourth goal of the playoffs on a breakaway just before the intermission to restore the three-goal lead.
Ottawa hadn't overcome a deficit bigger than one goal in the postseason and Neal ensured there would be no meltdown by the Penguins. A pair of sizzling wrist shots in the third period gave him his first career playoff hat trick and sent the Penguins roaring into hockey's final four.
NOTES: Pittsburgh went 1 for 3 on the power play and improved to 6-0 when it outscores an opponent on special teams in the postseason. ... Ottawa is 0-6 in franchise history when it falls behind 3-1 in a series.
A brief visual task can predict IQ, according to a new study.
This surprisingly simple exercise measures the brain's unconscious ability to filter out visual movement. The study shows that individuals whose brains are better at automatically suppressing background motion perform better on standard measures of intelligence.
The test is the first purely sensory assessment to be strongly correlated with IQ and may provide a non-verbal and culturally unbiased tool for scientists seeking to understand neural processes associated with general intelligence.
"Because intelligence is such a broad construct, you can't really track it back to one part of the brain," says Duje Tadin, a senior author on the study and an assistant professor of brain and cognitive sciences at the University of Rochester. "But since this task is so simple and so closely linked to IQ, it may give us clues about what makes a brain more efficient, and, consequently, more intelligent."
The unexpected link between IQ and motion filtering was reported online in the Cell Press journal Current Biologyon May 23 by a research team lead by Tadin and Michael Melnick, a doctoral candidate in brain and cognitive sciences at the University of Rochester.
In the study, individuals watched brief video clips of black and white bars moving across a computer screen. Their sole task was to identify which direction the bars drifted: to the right or to the left. The bars were presented in three sizes, with the smallest version restricted to the central circle where human motion perception is known to be optimal, an area roughly the width of the thumb when the hand is extended. Participants also took a standardized intelligence test.
As expected, people with higher IQ scores were faster at catching the movement of the bars when observing the smallest image. The results support prior research showing that individuals with higher IQs make simple perceptual judgments swifter and have faster reflexes. "Being 'quick witted' and 'quick on the draw' generally go hand in hand," says Melnick.
But the tables turned when presented with the larger images. The higher a person's IQ, the slower they were at detecting movement. "From previous research, we expected that all participants would be worse at detecting the movement of large images, but high IQ individuals were much, much worse," says Melnick. That counter-intuitive inability to perceive large moving images is a perceptual marker for the brain's ability to suppress background motion, the authors explain. In most scenarios, background movement is less important than small moving objects in the foreground. Think about driving in a car, walking down a hall, or even just moving your eyes across the room. The background is constantly in motion.
The key discovery in this study is how closely this natural filtering ability is linked to IQ. The first experiment found a 64 percent correlation between motion suppression and IQ scores, a much stronger relationship than other sensory measures to date. For example, research on the relationship between intelligence and color discrimination, sensitivity to pitch, and reaction times have found only a 20 to 40 percent correlation. "In our first experiment, the effect for motion was so strong," recalls Tadin, "that I really thought this was a fluke."
So the group tried to disprove the findings from the initial 12-participant study conducted while Tadin was at Vanderbilt University working with co-author Sohee Park, a professor of psychology. They reran the experiment at the University of Rochester on a new cohort of 53 subjects, administering the full IQ test instead of an abbreviated version and the results were even stronger; correlation rose to 71 percent. The authors also tested for other possible explanations for their findings.
For example, did the surprising link to IQ simply reflect a person's willful decision to focus on small moving images? To rule out the effect of attention, the second round of experiments randomly ordered the different image sizes and tested other types of large images that have been shown not to elicit suppression. High IQ individuals continued to be quicker on all tasks, except the ones that isolated motion suppression. The authors concluded that high IQ is associated with automatic filtering of background motion.
"We know from prior research which parts of the brain are involved in visual suppression of background motion. This new link to intelligence provides a good target for looking at what is different about the neural processing, what's different about the neurochemistry, what's different about the neurotransmitters of people with different IQs," says Tadin.
The relationship between IQ and motion suppression points to the fundamental cognitive processes that underlie intelligence, the authors write. The brain is bombarded by an overwhelming amount of sensory information, and its efficiency is built not only on how quickly our neural networks process these signals, but also on how good they are at suppressing less meaningful information. "Rapid processing is of little utility unless it is restricted to the most relevant information," the authors conclude.
The researchers point out that this vision test could remove some of the limitations associated with standard IQ tests, which have been criticized for cultural bias. "Because the test is simple and non-verbal, it will also help researchers better understand neural processing in individuals with intellectual and developmental disabilities," says co-author Loisa Bennetto, an associate professor of psychology at the University of Rochester.

ABU DHABI (Reuters) - France's foreign minister on Saturday ruled out Iran taking part in a proposed Syriapeace conference, saying Tehran was involved in the conflict and had no desire for peace.
Laurent Fabius will host Russian Foreign Minister Sergei Lavrov and U.S. Secretary of State John Kerry at a dinner on Monday to discuss how to nudge Syrian President Bashar al-Assad and the Syrian opposition into the talks in Geneva.
Speaking aboard a French aircraft en route to Abu Dhabi in the United Arab Emirates, Fabius said there was no "magic wand" to get warring parties to the negotiating table even though it appeared Assad's government had agreed to attend.
Russia has said Iran must be included in the peace conference, which was jointly proposed by Moscow and Washington and could convene in the next few weeks.
But Fabius said Iran's presence in Syria through its officers who were "directing operations" and through its Hezbollah proxy demonstrated that it had no place at the negotiating table.
"Yes the Russians want Iran to take part in Geneva, but we're opposed because Iran is not after a political solution and on the contrary has thrown itself directly into that battle."
Iran has denied it has forces in Syria supporting Assad's army, saying the accusations were invented by the "true enemies of Syria".
Fabius also said that with complex negotiations coming up later in the year between major powers that include France, U.S. and Russia over Iran's nuclear program, allowing Iran to take part in the Syrian conference would complicate those talks.
The United States and European Union have so far shied away from directly arming the rebels, but have given them "non-lethal" support, while Arab backers like Qatar and Saudi Arabia send them weapons.
Fabius is due to meet UAE Foreign Minister Sheikh Abdullah bin Zayed al-Nahyan for talks on Saturday. The crisis in Syria and Iran's nuclear program will top the agenda, given Gulf Arab states' accusations about Tehran meddling in their affairs by stoking unrest.
