在IDE编辑器中终止的代码

Question

我仍然在学习Java和实践，并最终创建了下面的代码，但每次我在IDE编辑器中运行它时，它总是被终止控制台选项卡。希望有人能帮助我，

import java.util.Scanner;
public class Practice {

public static void main(String[] args) {
Scanner scan = new Scanner (System.in);
String response;
int x, y, total;    
    System.out.println("Input the first variable:");
    x = scan.nextInt();
    System.out.println("Input the second variable");
    y = scan.nextInt();
    System.out.println("How should we solve it?");
    System.out.println("(Add, Subtract, Multiply, Divide)");
    response = scan.nextLine();

    if (response.equals("Add")) {
        total = x + y;
        System.out.println("The sum of " + x + y + " is " + total);
    }
    else if (response.equals("Subtract")) {
        total = x - y;
        System.out.println("The difference of " + x + y + " is " + total);
    }
    else if (response.equals("Multiply")) {
        total = x * y;
        System.out.println("The product of " + x + y + " is " + total);
    }
    else if (response.equals("Divide")){
        total = x / y;
        System.out.println("The Qoutient of " + x + y + " is " + total);
    }
    
}

}

对于scanner，在请求一个整数之后，应该使用scan.nextline（）；两次。或者只要求第三个整数，将标题改为：“（1.加，2.减，3.乘，4.除）”

在这里找到了一个更好的解释：扫描器在使用next（）或nextFoo（）后跳过了nextLine（）？
