原程序的错误有：

1.a为int型。去掉‘派颤帆’

2.ATM1 atm = new ATM1 ， 类名要和前面的一致

3.加入int a = sc.nextInt()// 请加入此句 进而选择相尘雹应功能，

PS：程序已调好，试试吧。

import java.util.Scanner

public class ATM1 {

Scanner sc = new Scanner(System.in)

private String name = "lorin"

private double password = 123

private double money = 500

public void aloha(){

System.out.println("***********************")

System.out.println("* *")

System.out.println("* 欢迎使用ATM *")

System.out.println("* *")

System.out.println("* 制作人：lorin *")
