error while compile code using javac

[suri]

hi,

i dont have much knowledge on java. this is my code. i got it from a friend of mine. and i would like to use it. but when i create a class file there's an error occur. could anybody help me?

could you please post the comile time error?

[r035198x]

You failed to copy by missing some characters (most likely end closing brace).
Better ask your friend about it since he wrote it.

[Eranga]

And please use code tags when you post codes here, with properly indent. Un-formatted codes are really hard to read.
