取款余额不能超过两千！最低不低于0.01元。

1。取款余额不能超过两千！最低不低于0.01元！存钱最低不能低于0.01。

package ATM;

import java.util.Scanner;

public class ATM3 {
double balance = 3000.00;
Scanner in = new Scanner(System.in);
String go = "";

public void draw() {//取款
    System.out.println("请输入取款金额：");
    Scanner sc = new Scanner(System.in);
    double money = in.nextDouble();
    //取款余额不能超过两千！最低不低于0.01元！
    if(money <= balance - 0.01 && money - 2000 <= 0) {
        balance = balance - money;

    }else if(money > balance - 0.01) {
        System.out.println("余额不足！");
    }
    System.out.println(balance);
    }

public void deposit() {//存款
    System.out.println("请输入存款的金额：");
    double money = in.nextDouble();
    if(money % 0.01 != 0) {
        System.out.println("本机最低可存0.01元");
        balance = balance + money;
    }else {
        go += "本次存入：" + money + "元！";

    }


    System.out.println(balance);
    }



public static void main(String[] args) {
    new ATM3().draw();
    new ATM3().deposit();
}

}

if(money % 0.01 != 0)
为什么这么写，用 money >= 0.01比较好
