从一开始，我应该如何开始我的最低硬币项目，用户更改输入？

Question

该程序应该在开始时找到基于用户输入的更改使用的最小硬币。但是，我似乎从一开始就无法完全重新开始。在当前状态下，它每次开始时都会不断添加相同的数字，并且不会显示用户第二次读取的输出。编辑：代码格式

import java.util.Scanner; // Import Scanner class
public class Main
{
    public static void main(String[] args) {
        
            Scanner input = new Scanner(System.in); // Create a Scanner object
            
            int change = 0;
            int quarters = 0;
            int dime = 0;
            int nickels = 0;
            int pennies = 0;
            
        System.out.println("Please Enter Amount of Change (1-99) or ZERO to EXIT.");
        while (change == 0) {
            change = input.nextInt();
            
            while (change <= 0) {
                    System.exit(0);
            }
            while (change >= 25){
                change = (change - 25); quarters = (quarters + 1);
            
            }
            while (change >= 10) {
                change = (change - 10); dime = (dime + 1);
            }
            while (change >= 5) {
                change = (change - 5); nickels = (nickels + 1); // block of code to be executed if the condition is true
            }
                    pennies = change; // block of code to be executed if the condition is false
                

        System.out.println("You currently have: ");
        System.out.println("Quarters:" + quarters);
        System.out.println("Dimes:" + dime);
        System.out.println("Nickels:" + nickels);
        System.out.println("Pennies:" + pennies);
            }
    }
}

Answer 1

我相信我已经弄清楚了。我将所有整数重置为代码末尾的0，并添加了另一个与第一个位相同的打印语句。如果有人看到了这一点，并希望看到我已修复的代码，我将在下面发布。

解决方案：

    import java.util.Scanner; // Import Scanner class

public class Main {
    public static void main(String[] args) {
        
            Scanner input = new Scanner(System.in); // Create a Scanner object
            
            int change = 0;
            int quarters = 0;
            int dime = 0;
            int nickels = 0;
            int pennies = 0;
            
        System.out.println("Please Enter Amount of Change (1-99) or ZERO to EXIT.");
        while (change == 0) {
            change = input.nextInt();
            
            while (change <= 0) {
                    System.exit(0);
            }
            while (change >= 25){
                change = (change - 25); quarters = (quarters + 1);
            
            }
            while (change >= 10) {
                change = (change - 10); dime = (dime + 1);
            }
            while (change >= 5) {
                change = (change - 5); nickels = (nickels + 1); // block of code to be executed if the condition is true
            }
                    pennies = change; // block of code to be executed if the condition is false
                

        System.out.println("You currently have: ");
        System.out.println("Quarters:" + quarters);
        System.out.println("Dimes:" + dime);
        System.out.println("Nickels:" + nickels);
        System.out.println("Pennies:" + pennies);
        change = 0;
        quarters = 0;
        dime = 0;
        nickels = 0;
        pennies = 0;
        System.out.println("Please Enter Amount of Change (1-99) or ZERO to EXIT.");
            }
    }
}
