This simple exercise is meant to verify that  you

Explanation / Answer

You are getting these errors because you must not be declaring the class properly.

In Java, you have to write your public static void maistem.out.printlnn(String args[]) function inside a class.

Here is a sample:

class chegg

{

public static void mian(String args[])

{

System.out.println("Please rate my answer :) ");

}

}

Also do not forget to include this at the top of the file:

import java.io.*;

Make sure that you resolve all erros before running the program. The best way to ensure this is to use Eclipse for development of Java programs.

Cheers!
