Java uses nested loop to simulate ATM withdrawal business operation example

This paper illustrates how Java uses nested loops to simulate ATM withdrawal business operations. Share with you for your reference, as follows:

code:

package com.jredu.ch03;
import java.util.Scanner;
public class Work4 {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner scan = new Scanner(system.in);
        for (int i = 1; i < 4; i++) {
            System.out.print("请输入密码：");
            String pwd = scan.next();
            if (!pwd.equals("111111")) {
                //密码错误
                if(i==3){
                    System.out.println("密码错误，请取卡");
                }else{
                    System.out.println("密码错误，还有"+(3-i)+"次机会");
                }
            }else{
                //密码正确
                while(true){
                    System.out.print("请输入金额:");
                    int money = scan.nextInt();
                    if(money%100==0&&money>0&&money<=1000){
                        System.out.println("您取了"+money+"元");
                        System.out.println("交易完成，请取卡！");
                        return;
                    }else{
                        System.out.println("金额有误，请重新输入");
                    }
                }
                }
        }
    }
}
