Java 我有一段代码，我必须将IF-ELSE语句合并到其中，但是如果条目不在范围内，如何使其循环？

我只想循环这个代码直到输入正确的答案，有人能教我怎么做吗

    //enter marital status
    {Scanner keyboard = new Scanner(System.in);
    System.out.println("Please enter your Marital Status folowing the numbers given");
    System.out.println("0 = Single");
    System.out.println("1 = Married Filing Jointly or Qualifying Widow(er)");
    System.out.println("2 = Married Filing Seperately");
    System.out.println("3 = Head of Household");
    status = keyboard.nextInt();

    {
        if (status == 0) {
        System.out.println("You have selected single.");}
    else if (status == 1) {System.out.println("You have selected Married Filing Seperately or Qualifying Widoe(er).");}
    else if (status == 2) {System.out.println("You have selected Married Filing Seperatey");}
    else if (status == 3) {System.out.println("You have selected Head of Household");}
    else if (status > 3) {System.out.println("Invalid selection"); System.exit(0);}
    }

你可以简单地：

boolean valid = false;
while(!valid) {
    System.out.println("Please enter your Marital Status folowing the numbers given");
    System.out.println("0 = Single");
    System.out.println("1 = Married Filing Jointly or Qualifying Widow(er)");
    System.out.println("2 = Married Filing Seperately");
    System.out.println("3 = Head of Household");
    status = keyboard.nextInt();

    if(status >= 0 && status <= 3) {
        valid = true;
    else 
        System.out.println("Invalid selection");
}

String response = "You have selected: ";
    switch(status){
        case 0:
            response += "single";
        break;

        case 1:
            response += "Married Filing Seperately or Qualifying Widoe(er).";
        break;

        case 2:
            response += "Married Filing Seperatey";
        break;

        case 3:
            response += "You have selected Head of Household";
        break;
    }

System.out.println(response);

boolean valid=false；
while（！valid）{
System.out.println（“请在给出的数字后面输入您的婚姻状况”）；
System.out.println（“0=单个”）；
System.out.println（“1=已婚共同申报或符合资格的寡妇（er）”；
System.out.println（“2=单独提交）；
System.out.println（“3=户主”）；
状态=键盘.nextInt（）；
如果（状态>=0&&status谢谢，但我如何添加一条显示循环是否运行的消息？在高级中再次感谢。没有看到其余内容抱歉，可能此解决方案对您更准确，请查看答案中的编辑。
