public class BankCard {

int cardNumber;
String name;
int passWord;
int balance;
int idNumber;

public BankCard (int idNumber, String name) {

this.idNumber = idNumber;
this.name = name;
passWord = 666666;
balance = 0;
cardNumber = 62208888;
}

public boolean changePwd (int passWord) {

this.passWord = passWord;

return true;//修改密码成功
}

public boolean deposit (int moneyIn) {

this.balance += moneyIn;

return true;//存款成功
}

public boolean drawMoney (int moneyOut) {

this.balance -= moneyOut;

return true;//取款成功
}

public void printInformation () {
System.out.println("卡号：" + cardNumber +
"\n姓名：" + name +
"\n身份证号：" + idNumber +
"\n卡内余额：" + balance +
"\n当前密码：" + passWord);
}
}

希望可以给个采纳，谢谢

package cn.itcast.redis;

import java.util.Scanner;

public class BankCard {
private String user;
private String name;
private String password;
private double yu_e;
private String sfz;
public static Scanner sc = new Scanner(System.in);

public BankCard(String name, String sfz) {
this.name = name;
this.sfz = sfz;
}

public BankCard() {
}

public String getUser() {
return user;
}

public void setUser(String user) {
this.user = "62208888";
}

public String getName() {
return name;
}

public void setName(String name) {

}

public String getPassword() {
return password;
}

public void setPassword(String password) {
this.password = "666666";
}

public double getYu_e() {
return yu_e;
}

public void setYu_e(double yu_e) {
this.yu_e = 0;
}

public String getSfz() {
return sfz;
}

public void setSfz(String sfz) {
this.sfz = sfz;
}

//修改密码
public void changPwd() {
System.out.println("请输入新的密码:");
password = sc.next();
System.out.println("修改成功新的密码为:" + password);
}

public void deposit() {
System.out.println("请输入存储金额:");
double cun = sc.nextInt();
yu_e = cun;
System.out.println("成功存储" + cun + "总金额为:" + yu_e);
}

public void drawMoney() {
System.out.println("请输入取款金额:" );
double qu=sc.nextInt();
if (qu>yu_e){
System.out.println("您的余额不足");

}else {
yu_e -= qu;
System.out.println( "以取出:"+qu+"元,余额:"+yu_e);
}

}

public static void main(String[] args){
BankCard b=new BankCard();
while (true) {
System.out.println("修改密码请按1 存储金额请按2 取款请按3 退出请按0");
String a = sc.next();
switch (a){
case "1":b.changPwd();break;
case "2":b.deposit();break;
case "3":b.drawMoney();break;
case "0":return;
}
}

}
}

有什么需要改进的自己改一下用笔记本写的不容易!
