Java重启程序帮助

这就是你可以做的

有这样的标志

boolean quit = false;

一会儿附上您的选择

while(!quit){......}

和

设置

quit = true

编辑：

像这样

public static void main(String a[]) {    System.out.println("Welcome");    Scanner myinput = new Scanner(System.in);    boolean quit = false;    while (!quit) {        System.out     .println("Make your choise. n 1.Check a card number n 2.Quit.");        int choise = myinput.nextInt();        switch (choise) {        case 1: System.out.println("Enter your credit card number: "); break;        case 2: System.out.println("Are you sure?"); String answer = myinput.next(); if (answer.equals("yes")) {     System.out.println("Byee :)");     quit= true; } break;        default: System.out.println("Idiot!"); break;        }    }
