Java:不兼容的类型(int/boolean)

Question

import java.io.*;
public class AdamHmwk4 {
    public static void main(String [] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

        int counter1;
        int counter2;
        int counter3;
        String answer = "";

        System.out.println("Welcome to Adam's skip-counting program!");
        System.out.println("Please input the number you would like to skip count by.");
        counter1 = Integer.parseInt(br.readLine());

        System.out.println("Please input the number you would like to start at.");
        counter2 = Integer.parseInt(br.readLine());

        System.out.println("Please input the number you would like to stop at.");
        counter3 = Integer.parseInt(br.readLine());

        System.out.println("This is skip counting by" + counter1 + ", starting at" + counter2  + "and ending at" + counter3 +":");

        while (counter2 = counter3) {
            counter2 = counter2 + counter1;
            counter3 = counter2 + counter1;
        }
    }
}

我正在尝试制作跳过计数程序。当我编译此代码时，行 while(counter2 = counter3){ 显示为不兼容类型错误。编译器说它找到了一个“int”，但它需要一个“boolean”。请记住，我是新手，所以我还没有在 Java 类中学习 boolean 值。

Answer 1

您不能将值与赋值运算符 = 进行比较。使用 == 来比较您的值。改变

while(counter2 = counter3){

至

while(counter2 == counter3){
