Output is not coming

[dlmagers]

I am having trouble with this output was wondering if someone could offer a third eye to see what I am doing wrong.

public class ContestantTester
{

	public static void main(String[] args)
	{
		Contestant contestant = new Contestant("Jon Smith");

		System.out.print("Expected Name: Jon Smith------------------------------>");
		System.out.println("Actual Name: " + contestant.getWinnings());

		contestant.addWinnings(100.0);
		contestant.addWinnings(200.0);

		System.out.print("Expected Winnings: 300.0------------------------------>");
		System.out.println("Actual Winnings: " + contestant.getWinnings());

		System.out.print("Expected toString: [name=Jon Smith, winnings=$300.0]-->");
		
		// WHEN YOU PASS AN OBJECT REFERENCE TO PRINTLN, THE toString() METHOD
		// FOR THE CLASS (IN THIS CASE CONTESTANT) IS AUTOMATICALLY CALLED
		System.out.println("Actual toString: " + contestant);

		contestant.bankrupt();
		System.out.print("Expected Winnings: 0.0-------------------------------->");
		System.out.println("Actual Winnings: " + contestant.getWinnings());

		contestant.addWinnings(150.0);

		System.out.print("Expected Winnings: 150.0------------------------------>");
		System.out.println("Actual Winnings: " + contestant.getWinnings());

	}

}

Here is my Class:

public class Contestant
{
	private double winnings1 = 100.00;
	private double winnings2 = 200.00;
	private String Contestant;
	
	public Contestant(String Contestant)
	{
		String contestant = Contestant;
	}

	public void setWinnings1(double winnings1)
	{
		winnings1 = 100.00; //establishing the value as 100
	}
	
	public void setWinnings2(double winnings2)
	{
		winnings2 = 200.00; //establishing the value as 200
	}
	
	public String getContestant()
	{
			String contestant = Contestant;
			return contestant;
	}
			
	public Object bankrupt() {
		return null;
	}

	public String getWinnings() {
		int getWinnings = 100;
		getWinnings++;
		return null;
	}

	void addWinnings(double d) {
		
	}
	
}

The values that are coming up are NULL. What am I going wrong. I am new to this Java Programming and have done well so far but it doesn't seem like it is clicking for me at this point.

The values that are coming up are NULL.

Did you write the code? null is the value being returned by the methods:

return null;

Change the null to the value that you want to see returned by the method.
