将两个变量传递给一个方法以获得两个结果 [英] Passing two variables to one method to get two results

问题描述

我正在尝试将两个变量传递给一个方法，并让该方法给我带来两个独立的结果.

I am trying to pass two variables along to a method and have the method give me back two independent results.

int numX = 5;
int numY = 3;

System.out.println(displayTwiceTheNumber(numX, numY));

}
public static int displayTwiceTheNumber(int numX, int numY) {
    int numW, numZ;
    numW, numZ = 2 * (numX, numY);
    return numW numZ;        
}

Java认为在 numW，numZ = 2 *(numX，numY); 我正在尝试重新定义 numX 和 numY .我该如何在最后一个块中加上两个变量并给出两个结果呢?

Java takes it that at numW, numZ = 2 * (numX, numY); that I am trying to redefine numX and numY. How do I phrase the last block to take two variables and give two results?

推荐答案

单个int函数一次只能返回1个int.如果要返回2个值，请考虑两次调用该函数或创建一个要使用的自定义对象.

A single int function can only return 1 int at a time. If you want to return 2 values, consider calling the function twice or creating a custom object to be used.
