Question

我是初学者，这是为了学校。请帮我这个，它必须是一个非常简单的程序，用户输入两个数字，结果是两个数字，一个hcf和一个gcd。我分开编写了代码，但我不知道如何将它们组合起来。

Answer 1

转到GCD程序并获取计算GCD的代码并将其移动到函数中：

public int GCD(int a, int b) {
    //find GCD
    //return GCD
}

为HCF做同样的事情：

public int HCF(int a, int b) {
    //find HCF
    //return HCF
}

然后在主要方法中：

//all the code for prompting the user for input
//and all the code for asking the user for input
//code which you've already written if you wrote these two programs independently already
System.out.println("GCD of " + input1 + " and " + input2 + " is " + gcd(input1, input2));
System.out.println("HCF of " + input1 + " and " + input2 + " is " + hcf(input1, input2));

同时给出两个数字的hcf和gcd的程序
