本文介绍如何使用Java编程创建一个Account类，包含id、password、name、personId、email和balance等属性，以及deposit和withdraw方法进行存款和取款操作。此外，还提供了有参构造器用于初始化属性，并通过test方法展示成员变量信息。

题目：创建一个账户Account类，该类有id:账户号码(字符串类型),password:账户密码(int),name:真实姓名(字符串类型),
personId:身份证号码(字符串类型),email:客户的电子邮箱(字符串类型),balance:账户余额(double)。
存款方法:deposit(double balance),取款方法:withdraw(double balance)。构造方法:有参和无参,有参构造方法用于设置必要的属性
并且通过test()方法将所有成员变量打印出来，调用存款和取款方法

Account类：
public class Account {
    private String id;
    private int password;
    private String name;
    private String personId;
    private String email;
    private double balance;

    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public int getPassword() {
        return password;
    }
    public void setPassword(int password) {
        this.password = password;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPersonId() {
        return personId;
    }
    public void setPersonId(String personId) {
        this.personId = personId;
    }
    public String getEmail() {
        return email;
    }   
    public void setEmail(String email) {
        this.email = email;
    }
    public double getBalance() {
        return balance;
    }
    public void setBalance(double balance) {
        this.balance = balance;
    }

    public Account() {

    }
    public Account(String id, int password, String name, String personId, String email, double balance) {   
        this.id = id;
        this.password = password;
        this.name = name;
        this.personId = personId;
        this.email = email;
        this.balance = balance;
    }

    @Override
    public String toString() {
        return "Account [id=" + id + ", password=" + password + ", name=" + name + ", personId=" + personId + ", email="
                + email + ", balance=" + balance + "]";
    }
    //存钱
    public void deposit(double money){
        balance += money;
    }
    //取钱
    public void withdraw(double money){
        if(balance <= 0){
            System.out.println("余额不足");
        }else{
            balance -= money;
        }
    }
}
Test类：
public class Test {
    public static void main(String[] args) {
        Account a = new Account("123",000,"张三","341221","110@qq.com",200);
        System.out.println(a.toString());
        a.deposit(100);
        a.withdraw(50);
    }
}
