我已經創建了一個賬戶類，但是在第一次計算之後，它會繼續並將第二行加倍。我錯過了代碼中的任何東西嗎？賬戶類Java OOP
public class Account
{
private double balance; //STATE
private double interestRate; //STATE
private double rate;//STATE
public Account()
{
balance = 0;
interestRate = 0;
}
public Account(double amount, double interestRate)
{
balance = amount;
rate = interestRate;
}
public void deposit(double amount)
{
balance=balance+amount;
}
public void withdraw(double amount)
{
balance = balance - amount;
}
public void setInterest(double rate)
{
balance = balance + balance * rate;
//this.setInterst = setInterest;
//setInterest = InterestRate/12;
}
public double computeInterest(int n)
{
balance=Math.pow(balance*(1+rate),n/12);
return balance;
}
public double getsetInterest()
{
return rate;
}
public double getBalance()
{
return balance;
}
public void close()
{
balance =0;
}
}
public class TestAccountInterest
{
public static void main (String[] args)
{
Account acc1 = new Account(500, 0.1);//0.10);
Account acc2 = new Account(400, 0.2); //0.20);
/*************************************
ACC1 ACCOUNT BELOW
*************************************/
acc1.deposit(500);
acc1.withdraw(300);
acc1.computeInterest(12);
acc1.computeInterest(24);
System.out.println(acc1.computeInterest(12));
/**************************************
ACC2 ACCOUNT BELOW
**************************************/
acc2.withdraw(200);
acc2.deposit(800);
acc2.computeInterest(24);
System.out.println(acc2.computeInterest(24));
}
}
我不知道我是否錯過了某些東西或者我寫錯了代碼。
輸出是什麼？預期的產出是什麼？ –
這是一個例子，但預期的輸出應該是12個月-110，24個月-122 – Omor
而且你稱它爲12個月，然後是24個月，然後是12個月？每個人都改變了對象？ –
