Assume a bank account begins with a balance of $100 and earns interest at an annual rate of 5%.  The interest is computed at the end of each year using the following formula:
 newBalance = previousBalance * (1 + interestRate)
 Write a Java program named ComputeInterest.java to compute and display this account balance at the end of each year for a five-year period.  Do not use loops

我对题意也不是很清楚...
是不是打印出:每年的年底的总金额(5年之内的)?
我还没领会面向对象的思想...
我只会用循环做,不过感觉是面向过程的程序..

public class ComputeInterest {
        
    /**
     * Creates a new instance of <code>ComputeInterest</code>.
     */
    public ComputeInterest() {
    }
   
    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here
        double interest=1.05;
        double OldBalance=100;
       // double NewBalance;
        
        int i;
        for(i=0;i<5;i++)
        {
         double NewBalance=interest*OldBalance;
         System.out.println("NewBalance"+NewBalance);
         OldBalance=NewBalance;
        }
      
    }
}
这个是我写的使用循环的...谁能帮我看下,如何写不使用循环的....菜鸟求救

哇，英文的！

public class ComputeInterest {
    double interest=1.05;
    double OldBalance=100,NewBalance;
   public ComputeInterest(int i) {
        do{
            NewBalance=OldBalance*interest;
            OldBalance=NewBalance;
            i--;
        }while(i>0);
    }
  public static void main(String[] args) {
     for(int i=1;i<=5;i++)
        {
         System.out.println("NewBalance"+new ComputeInterest(i).NewBalance);
          }
       }
}
我构造函数用了个循环,这样行吗?

不用循环可以用递归。像这样：
package com.test;

public class TestRex {
    static double balance = 100;
    static double rate = 0.05;
    /**
     * @param args
     */
    public static void main(String[] args) {
        getNewBalance(1);
    }
    
    static void getNewBalance(int year){    
        if(year>5) {
            return;
        }else{
            balance = balance*(1+rate);
            System.out.println(balance);
        }
        year++;
        getNewBalance(year);
    }

}

个人感觉循环比用递归要好……

本质上大家做的都是循环。。。不知道ls是什么意思啊？

这是人家题目的要求，Do not use loops

谢谢大家的支持....
