    Default Formatting my output

    How do I change my numbers at the end so that instead of showing 0 it shows 0.00 or instead of showing 5.3 it shows 5.30?
    I want only the winnings to be showing in this format.

     
    import java.util.Scanner;
     
    public class part1 {
     
    public static void main(String[] args) 
    	{
    		Scanner keyboard = new Scanner(System.in);
    		double stake;
    		String horsesName;
    		double outrightWinOrEachWay;
    		double outrightWin;
    		double eachWay;
    		double OddsX;
    		double OddsY;
    		double totalOdds;
    		double eachWayOdds;
    		double runners;
    		double finishingPosition;
    		double winnings;
    		double win;
    		double place;
     
     
    				System.out.println("Please enter your stake:");
    				while (! keyboard.hasNextDouble() )

    				} 
    				stake = keyboard.nextFloat(); 
     
     
    				horsesName = keyboard.nextLine(); 
     
    				while ( horsesName.isEmpty() ) 
     
    				{ 
    				 System.out.print("What is your horses name?"); 
    				 horsesName = keyboard.nextLine(); 
    				} 
     
    				horsesName = horsesName.toUpperCase();

    Use the NumberFormat or DecimalFormat class.

    The forum formatting tag is "code" and not "java".

    You go to the Java API and read about them. You google for examples. Don't just sit there and expect to be spoonfed.

    I have tried that and it hasn't worked, I'm not just waiting to be spoonfed, I came on a website that was supposed to help.

    I did help you. I told you what class you need to use. But as far as I can tell you did nothing with that information and are simply demanding more help.

    You claim "it hasn't worked". That provides zero information. Did you code get deleted? Did your cat explode? Did all the women in the world grow beards? WHAT? Post the code that you tried and fully explain what the problem is. If you get errors then copy and paste the full and exact error messages.
