自带测试类
源代码：

package testaccount; public class TestAccount{ public static void main(String args[]){ Account ss=new Account(1122,20000); ss.setannualInterestRate(4.5); ss.withDraw(2500); ss.deposit(3000); System.out.println("The ss's id is "+ ss.getid()); System.out.println("The ss's balance is "+ ss.getbalance()); System.out.println("The ss's dateCreated is "+ ss.getdateCreated()); } } class Account{ private int id=0; private double balance=0; private double annualInterestRate=0; private java.util.Date dateCreated=new java.util.Date(); public Account(){ } public Account(int newid,int newbalance){ id=newid; balance=newbalance; } public int getid(){ return id; } public double getbalance(){ return balance; } public double getannualInterestRate(){ return annualInterestRate; } public void setid(int newid){ id=newid; } public void setbalance(double newbalance){ balance=newbalance; } public void setannualInterestRate(double newannualInterestRate){ annualInterestRate=newannualInterestRate; } public double getMonthlyInterest(){ return (annualInterestRate/12)/100; } public String getdateCreated(){ return dateCreated.toString(); } public void withDraw(double draw){ balance-=draw; } public void deposit(double draw){ balance+=draw; } }
