The major difference between C++ and Java is that not everything is a class. In particular, the main function is part of the 'top level', so get rid of the class definitions.

Becuse it's part of the top level, the public and static keywords have no meaning.

The main function can return an integer value to the calling environment (usually 0), but if you don't care, just declare the function void
Also, if you don't want to use the command line arguments, don't declare them.

Now for the I/O. Well, just O really. First of all, all the Java I/O classes are in the java.io package.
