題目說明

請參考底下程式碼，並請寫一個計算式為(x - y) * (x + y / 2)的函式

public class MyProgram {
    public static void main(String[] args) {
        // call a function to increment 0.5
        int value = 5;
        System.out.println(value);
        double newValue = increment(value, 0.3);
        System.out.println(newValue);
    }

    // function to increment a value
    public static double increment(int x, double y) {
        double result = x + y;
        return result;
    }
}

import java.util.Scanner;

public class t04111 {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int x = in.nextInt();
        int y = in.nextInt();
        in.close();
        int newValue = increment(x, y);
        System.out.println(newValue);
    }

    // function to increment a value
    public static int increment(int x, int y) {
        int result = (x - y) * (x + y / 2);
        return result;
    }
}
