You're welcome.

First, make two integer arrays (which have 4 (<- number of variables) slots)) and then set first integer array's values to variables a, b, c and d. After that, make a for loop which scans through the array and if a number is not equal to zero, it puts the variable in the second array. When that is over, you scan through the second array and check if numbers are equal to each other. In code it would be something like this:

public static void main(String[] args) {
		int a = 0;
		int b = 7;
		int c = 0;
		int d = 9;
		int[] integers = {a, b, c, d};
		int[] notZeros = new int[4];
		
		for(int i = 0; i < integers.length; i++){
			if(integers[i] != 0)
				notZeros[i] = integers[i];
		}
		
		for(int i = 0; i < notZeros.length; i++){
			int current = integers[i];
			if(current == integers[0]){
				if(i != 0){
					// Your code.
				}else break;
			}
			
			if(current == integers[1]){
				if(i != 1){
					// Your code.
				}else break;
			}
			
			if(current == integers[2]){
				if(i != 2){
					// Your code.
				}else break;
			}
			
			if(current == integers[3]){
				if(i != 3){
					// Your code.
				}else break;
			}
		}
	}

Please excuse me. I've made a mistake there. This is the right way for the last for loop:

		for(int i = 0; i < notZeros.length; i++){
			int current = notZeros[i];
			if(current == notZeros[0]){
				if(i != 0){
					// Your code.
				}else break;
			}
			
			if(current == notZeros[1]){
				if(i != 1){
					// Your code.
				}else break;
			}
			
			if(current == notZeros[2]){
				if(i != 2){
					// Your code.
				}else break;
			}
			
			if(current == notZeros[3]){
				if(i != 3){
					// Your code.
				}else break;
			}
		}

I'm so sorry, but I cannot edit my posts for some reason. I accidently put else break at the end of each if statement. This could also be done in an easier way. Argh, I failed a bit.

Anyway, just remove that else break;.

To check if a variable is not equal to zero, do this:

if(variable != 0){
   // Your code here.

To check if integer variables equal to integer variables, do this:

if(variable1 == variable2){
   // Your code here.
}

But, it's different with strings; Here is the way to do it with strings:

if(string1.equals(string2)){
   // Your code here.
}

Usually when that happens, you need to give value to the variable.

For example:

String whichDay = null;

You could simply use two JPanels and then when you die, just switch them. That's kind of what I did on the game I'm currently developing since I don't want to use any libraries.

public synchronized void switchPanels(JPanel newPanel){
	this.remove(panel);
	this.panel = newPanel;
	this.add(panel);
	this.setTitle(panel.getName()); // Delete this line if the name stays the same.
	this.validate(); // Very important line. Don't delete it.
}

(In order for this code to work, your class needs to extend JFrame.)
