Instead of giving us questions to see if we know java, why don't you try writing the code yourself. If you run into problems, show us what you have done, show us the output you're trying to get, show us the output you are getting, and show us any diagnostics your code is producing. Maybe we can help you learn from your mistakes instead of doing all of the work for you (so you don't learn anything at all).

Sorry, I usually like to look at complete code first to learn and then try.
I wrote this:

Code:

public class prob1
{

    public static void main( String[] args )
    {
	 Scanner user_input = new Scanner(System.in);
	 
	 String name;
	 System.out.print("Enter your first name: ");
	 name = user_input.next();
	 
	 int i;
	 int n = 100;
	 for (i=0; i<n; i++)
		System.out.print(name);

    }

}

I am not sure if it works or not because I do not know how to run it on the command line. I tried java prob1 and received this error: Error: Could not find or load main class prob1
Then I tried javac prob1 (I thought this would compile it) but I received this:
error: Class names, 'prob1', are only accepted if annotation processing is explicitly requested
I never tried running a java code on unix. I wrote the code using vim.
