java - 在哪里正确放置 while-do 语句？

Question

我不久前刚刚开始编程，我真的很想了解更多。现在，我正在创建一个小的“if-else”、“while-do”场景，用户将在其中使用正确的整数回答问题。不过，每当我遇到这部分代码时，我都会遇到麻烦:

if (chopperCrash > 100) {   


        System.out.println("That's not possible!");

        System.out.println("Hurry and re-enter a new value before we crash!");
        continue;

它不断循环打印文本。有人可以帮助我完成这个特定的项目，并向我详细解释“if-else”和“while-do”语句的正确放置吗？感谢您的任何帮助。如果这个问题已经得到回答，我很抱歉，而且我太笨了，无法理解之前提出的其他问题。这是我的完整代码块:

import java.util.Scanner;

public class FirstClass {
public static void main (String[] args){

    System.out.println("The chopper is going down because your lack of experience.");

    System.out.println("How much throttle are you going to give it?");

    System.out.println("(enter a number between 1 and 100)");

    Scanner FirstScan = new Scanner(System.in);


    int number = FirstScan.nextInt();
    int chopperCrash = number;

    while (true){       

    if (chopperCrash >= 60 && chopperCrash <= 100){

        System.out.println("Looks like we'll make it another day!");
        break;
    }

        else{       

    if (chopperCrash > 100) {   


        System.out.println("That's not possible!");

        System.out.println("Hurry and re-enter a new value before we crash!");
        continue;
    }
    else{
    if (chopperCrash <= 59) {
        System.out.println("Not enough throttle!");
        System.out.println("We're going down!");

        break;
             }
           }
         }
      }
   }
}

您将输入代码排除在循环之外:

int number = FirstScan.nextInt();
int chopperCrash = number;

while (true) {

由于您从未在循环内分配chopperCrash，因此它会永远持续下去。所以，像这样把它放进去:

while (true) {
    int number = FirstScan.nextInt();
    int chopperCrash = number;
