Hello Pooja,

Using Console API( In Java 6) to output formatted content is much easy.

You can call : console.format(String fmt, Object... args)
OR
console.printf(String fmt, Object... args) to print formatted data

And The main method for handling user-input : readLine().

This method ( readLine(String fmt, Object... args) ) is a combination of formatted output with user input. The method uses the java.util.Formatter syntax for the first argument, and applies the results of the args array.

Example:

import java.io.*;

public class ConsoleExample 
{
	public static void main(String[] args){
		Console console = System.console();
		if(console != null) {
			 String formatString = "%1$4s %2$5s %3$10s%n";
			 String name = console.readLine(formatString,"Please","Enter","Your Name :");
		}
	}
}

If any doubt please let me know.

Hi Pooja,

You can also see the Console API in action in my small tutorial at:
