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.

native2ascii

native2ascii(1) 					      General Commands Manual						   native2ascii(1)

NAME

       native2ascii - native to ASCII converter

SYNOPSIS

       native2ascii [ options ]
	    [ inputfile [outputfile]]

DESCRIPTION

       The  Java  compiler  and  other	Java  tools  can  only process files that contain Latin-1 or Unicode-encoded (udddd notation) characters.
       native2ascii converts files that contain other character encoding into files containing Latin-1 or Unicode-encoded charaters.

       If outputfile is omitted, standard output is used for output.  In addition, if inputfile is omitted, standard input is used for input.

OPTIONS

       The following options are supported:

       -encoding encoding_name
	    Specifies the encoding name that is used by the conversion procedure.  The default encoding is taken from system property  file.encod-
	    ing.   The encoding_name string must be one taken from the first column of the table of supported encodings in the Supported Encodings
	    document:

	    http://java.sun.com/j2se/1.5/docs/guide/intl/encoding.doc.html

       -reverse
	    Performs the reverse operation: converts a file with Latin-1 or Unicode-encoded characters to one with native-encoded characters.

       -Joption       Pass option to the Java virtual machine, where option is one of the options described on the man page for the java  applica-
		      tion  launcher, java(1). For example, -J-Xms48m sets the startup memory to 48 megabytes. It is a common convention for -J to
		      pass options to the underlying virtual machine.
