在Java中，如何使变量随每个方法调用而变化？

Question

I'm trying to create a program that does manual division for whole numbers and prints out the quotient and remainder. I know Java can't change primitives so I would have to use a return type, but I'm not entirely sure how to incorporate it. Here's what I have so far:

public class Division
{
    private int x;
    private int y;
    private int quo;
    private int a;

    public Division() {
        x = 50; //these two are just temporary for testing
        y = 5;
        quo = 0;
    }

    public void divide() {
        a = (x-y);
        quo++;
    }

    public void checkComplete() {
        if(a > y) {
            this.divide();
        }
        else {
            System.out.println("Quotient: " + quo);
        }
    }

    public static void main (String[] arg) {
        Division math = new Division();
        math.divide();
        math.checkComplete();
    }
}

I'm trying to have the variable a change to the output in method divide for future method calls. Any help is appreciated.

Answer 1

In order to do the division you have to call your divide method several times until a < y ...

Looking at the code, I see you have this:

public void checkComplete() {
    if(a > y) {
        this.divide();
    }
    else {
        System.out.println("Quotient: " + quo);
    }
}

Shouldn't you have a while (a>=y) { ... } somewhere there ? Maybe instead of that if ?
