我有一个关于Java中的构造函数的多个实例的问题.

我的任务是接收两个分数,然后乘以并除以这些分数.

我不确定如何为类对象本身的实例提供单独的值.

以下是我遇到问题的示例代码:

import java.util.Scanner;

public class TextLab05
{
    static int num1, den1;   // numerator and denominator of the 1st rational number
    static int num2, den2;   // numerator and denominator of the 2nd rational number

    public static void main (String args[])
    {
        enterData();

        Rational r1 = new Rational(num1,den1);
        Rational r2 = new Rational(num2,den2);
    }
}

class Rational
{

    private int firstNum;   // entered numerator
    private int firstDen;   // entered denominator
    private int num;        // reduced numerator
    private int den; …
