Thread: Help! Variable potentially getting Overwritten!

Can you post the program's output that shows what you are talking about?
I don't see where you set the value of score to 0.

Please edit your post and wrap your code with

Why isn't 0 a valid value? The value of score is only changed if one of the if statements is true.
If they are all false, the value won't be changed. Which if statement(s) are true?
Try debugging the code by adding println statements to print out the value of answer and the value of contents of the solutions array.
The Array class's toString() method will make printing array contents easier:

System.out.println("an ID "+ java.util.Arrays.toString(theArrayName));

What data type is answer? If it's an object, you need to use the equals() method not == to compare it.
== is for primitives like int.

Integer is a class. But sometimes the compiler will automatically extract its contents and retrieve the int value it holds using a hidden process called unboxing.

they didn't output anything

That would mean that they were not executed. Move them outside of any if statements so that they are sure to execute. Like before the first if
and after the last else.

Can you post what was printed out and the code that did the printing?
The printout should show the values of: answer, totalquestions and the full contents of solutions.

Did you also consider the value of totalquestions?

Total questions isn't an issue. I already fixed that problem, it's in a different section of the code, so it wasn't part of the printout.

 
    System.out.println("answer:"+answer);
    System.out.println("solution:"+ java.util.Arrays.toString(solutions));
    buttonPressA();
    buttonPressB();
    buttonPressC();
    buttonPressD();
 
    int Score=0;
    if (totalquestions.equals(1)){
        txta_display.setText("What is the slope of a line containing (4,2) and (8,4)?\n A. 2\n B. 3\n C. 13\n D. 1");
        if (answer==solutions[0]) {
             score=score+1;
 
        }
 
        System.out.println("Score: "+Score);
    }
    else if (totalquestions.equals(2)){
        txta_display.setText("Question");
        if (answer==solutions[1]){
            score=score+1;
 
        }
        System.out.println("Score: "+Score);
 
    }
    else if (totalquestions.equals(3)){
        txta_display.setText("Question");
     if (answer==solutions[2]){
         score=score+1;
 
     }
        System.out.println("Score: "+Score);
 
    }
    else if (totalquestions.equals(4)){
    txta_display.setText("Question");
    if (answer==solutions[3]){
        score=score+1;
 
    }
    System.out.println("Score: "+Score);
 
    }
    else if(totalquestions.equals(5)) {
        txta_display.setText("Question");
        if (answer==solutions[4]){
            score=score+1;
 
        }
        System.out.println("Score: "+Score);
 
    }
    else if(totalquestions>5){
        txta_display.setText("You have finished! Your score is"+score+"out of 5.");
    }

Printout is as follows:
answer:null
solution:[1, 2, 4, 3, 4]
Score: 0
answer:1
solution:[1, 2, 4, 3, 4]
Score: 0
answer:2
solution:[1, 2, 4, 3, 4]
Score: 0
answer:4
solution:[1, 2, 4, 3, 4]
Score: 0
answer:3
solution:[1, 2, 4, 3, 4]
Score: 0
answer:4
solution:[1, 2, 4, 3, 4]
0

You forgot to print out the value of totalquestions. Its value controls what solutions element answer is compared against.

If answer can have a null value then it is an object and you should use a method to compare it, not the == operator.

You have this same print out several places. How do you know which one printed?

System.out.println("Score: "+Score);

Add something to different to each String to make each unique:

System.out.println("1 Score: "+Score);
