开始Java编程

好的，我正在为我的Java编程类做一个作业。作业如下（代码将在末尾）： 假设一所大学今年的学费是10000美元，每年增加5%。编写一个程序，计算十年内的学费和十年内四年学费的总成本。金额应精确到小数点后两位。我不知道哪里出了问题，怎么解决。当我尝试运行它时，什么都没有发生，什么都没有显示（这是我的密码：

public class FutureTuitionPrice {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        double tuition = 10000;
        double count = 0;
        double increase = 1.05;
        double increasedTuition = 0;

        do {
            increasedTuition = tuition * increase;

        } while(count <=10);
        count++;

        if (count ==10);
        System.out.print("Tuition in ten years is $ \n" + increasedTuition);        
        do {
            increasedTuition = tuition * increase;
        }while (count==10 && count < 14);
        count ++;
         if (count ==14);
         System.out.print("The four-year tuitiuon in ten years is $ " + increasedTuition);
        }

    }

}当（count=10&&count在纸上执行do/while循环，并在每次迭代时记下count变量的值。你的循环是永无止境的。调试代码。将来也会有所帮助。对于程序员来说，最重要的技能是。如果你坐下来使用eclipse调试器并学习如何使用它，你会发现自己有一个更好的pr现在和将来很多事情都会变得更容易。调试器在哪里？它将捕获代码中没有立即显示的问题？谢谢！我现在就去试试！那么，我在下一个循环中做得对吗（从计数10到14计算4年的学费？）那么你为什么不把它写对而不是建议？@mikeTheLiar好的，老板：）好的，我确实改变了这一点，程序现在运行了，但它只进行了一次迭代，所以显示的两个数字的结果都是一样的。@塔米，你应该试着回答关于这个问题的评论，而不是让别人帮你修改代码并指出每一个小错误。否则，你会发现自己处于相同的情况n在每一个即将到来的家庭作业中。你应该检查语法。不要将
do while
循环与
while
循环混合。是的，谢谢，我不知道我的心思在哪里，修复了代码片段，问题仍然是他从未增加过计数。
