Hi I am a beginner in Java and I am creating a Calculator Application.
I have the GUI displaying and if I click a digit it will display the digits but when I click two digits simultaneously just the last digit clicked will display.

I know I need to declare a String but I am not sure how to do this.

Any assistance would be greatly appreciated.

This is my code for the method.

package calculator;

public class CalculatorController {

	private final CalculatorModel model;
	public String displayNumbers = ""; 

	public CalculatorController(CalculatorModel model) {
		this.model = model;
	}
	
	public void buttonPushed(String buttonLabel) {
		if (buttonLabel.equals("C")){
			model.setDisplay("0.");
		}
		
		else
			model.setDisplay(buttonLabel + "");
			
		}
		
	}

not very much to look at
what does setDisplay() do ?
What is buttonLabel ?
buttonLabel + "" is exactly the same thing as the original buttonLabel.
May be beside the setDisplay() method you also need a appendToDisplay() method.

Well, it is very difficult to help you with just this method so I suggest you post your entire code as some methods which you have used here don't have any definition. So, once you post the entire code, we will certainly be in a better position to help you.

I figured it out thank you for your help.

In future I will post up all the code.
