Question

编写一个Java程序Suansu.java,定义两个整型变量a和b,使用构造方法初始化a为10,b为5,并定义求出a与b的和(方法名为AddAB),差(方法名为(SubAB) 积(方法名为MultiAB),商(方法名为DivAB)的方法。用另一个Java程序TestSuansu.java测试Suansu.java定义的方法,并在屏幕上输出结果。

package com.example.demo.csdn;

public class Suansu {

    private int a;
    private int b;

    public Suansu(int a, int b) {
        this.a = a;
        this.b = b;
    }

    public int AddAB() {
        return a + b;
    }

    public int SubAB() {
        return a - b;
    }

    public int MultiAB() {
        return a * b;
    }

    public int DivAB() {
        return a / b;
    }

    public static void main(String[] args) {
        Suansu test = new Suansu(10, 5);
        int AddAB = test.AddAB();
        int subAB = test.SubAB();
        int multiAB = test.MultiAB();
        int divAB = test.DivAB();
        System.out.println(AddAB);
        System.out.println(subAB);
        System.out.println(multiAB);
        System.out.println(divAB);
    }
}
