[英]Why is my while loop printing out the same thing each time?
对不起,我知道这个问题每天可能会被问一百万次,但我真的找不到我正在寻找的答案。 我是 Java 的初学者(我正在上大学,正在学习一堆新语言),我的 while 循环每次都打印出同样的东西。
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("What is the loan amount? ");
int amount = scanner.nextInt();
int x = 1;
//your code goes here
while (x < 6){
System.out.println("Month " +x+ ":");
int percent = (amount / 10);
System.out.println("Payment: 10 percent of " +amount+ " = " +percent);
int rAmt = amount - percent;
System.out.println("Remaining amount: " +rAmt);
x++;
}
}
}
所以问题是,在 while 循环中进行计算后,您永远不会真正改变amount
。 我认为你想要做的是设置amount = rAmt;
,这将产生以下代码。 这将导致每次迭代减少 10% 的数量,并将这个新值结转。
...
//your code goes here
while (x < 6){
System.out.println("Month " +x+ ":");
int percent = (amount / 10);
System.out.println("Payment: 10 percent of " +amount+ " = " +percent);
int rAmt = amount - percent;
System.out.println("Remaining amount: " +rAmt);
amount = rAmt;
x++;
}
