如何讓用戶輸入進入for循環並使程序循環直到用戶輸入退出

Question

如何讓用戶輸入進入 for 循環並使程序循環直到用戶輸入退出？

這是我的代碼：

System.out.println("what is your full name?" );
Name = scan.nextLine();
String newString = Name.replaceAll(" ", "");
System.out.println("please enter " + newString.length() + " numbers and the total will be calculated");

if (newString.length() == 3) {
    for(int count = 1; count <= newString.length(); count++)
        System.out.println( "Number " + count + ":" + );
    Num1 = scan.nextInt();
    Num2 = scan.nextInt();
    Num3 = scan.nextInt();
    System.out.println("total is " + (Num1 + Num2 + Num3));
}

在 for 循環中試試這個：

    boolean flag = true;
    while(flag) {
        String input = scan.nextLine();

        if (input.equals("quit")){
            flag = false;
        } else {
            //Your code here
        }
    }
