java - 为什么这会给我一个无限循环？

Question

我正在检查用于计算投资的代码，直到它翻倍，并且我收到了一个我似乎无法解决的无限循环。谁能弄清楚为什么这会给我一个无限循环？我自己经历过，但似乎找不到问题所在。所指的“期间”是指每年复利多少次。

double account = 0; //declares the variables to be used
   double base = 0;
   double interest = 0;
   double rate = 0;
   double result = 0;
   double times = 0;
   int years = 0;
   int j;

   System.out.println("This is a program that calculates interest.");
   Scanner kbReader = new Scanner(System.in); //enters in all data  
   System.out.print("Enter account balance: ");
   account = kbReader.nextDouble();
   System.out.print("Enter interest rate (as decimal): ");
   rate = kbReader.nextDouble();

   System.out.println("                    " + "Years to double" + "     " +     "Ending balance");
   base = account;
   result = account;
   for (j=0; j<3; j++){
       System.out.print("Enter period: ");
       times = kbReader.nextDouble();
       while (account < base*2){
           interest = account * rate / times;
           account = interest + base;
           years++;
       }
        account = (((int)(account * 100))/100.0);
       //results
       System.out.print("                         " + i + "               " + account + "\n");
       account = result;
   }

代码应要求三个“周期”，或输入数据每年复合的三个不同时间(例如每年、每月、每天等)

非常感谢!

Answer 1

而不是做

account =interest +base

你应该有

account = interest +account
