poj机上的JAVA那些事儿

　　Recently I've been working on problems in POJ, which is really tough with JAVA.

　　Okay,things to be paid attention to include:

　　First, your class name should be "Main" rather than any other name you use to differenciate it from others.

　　Second, after comparing mine with the standard answers, I noticed that all of the methods are modified with "public" in a class in the standard answers. That is wierd. uhh...

　　Okay, with the two, I still got "Wrong answer" as the results of my submitted resources.

　　Even More,Java works rather too slowly and costs so much  memory.

　　What a sad story!
