如果语句总是给予同样的答案 [英] If statement always giving the same answer

问题描述

import java.util.Scanner;

class Practice {

public static void main(String args[]) {

    System.out.println("Enter the number of treats you have:");
    Scanner treatsScanner = new Scanner(System.in);
    int treats = (treatsScanner.nextInt());

    System.out.println("Enter the number of hamsters you have:");
    Scanner hamstersScanner = new Scanner(System.in);
    int hamsters = (hamstersScanner.nextInt());

    System.out.println("How many treats does each hamster need?");
    Scanner neededTreatsScanner = new Scanner(System.in);
    int neededTreats = (neededTreatsScanner.nextInt());     

    int treatsPerHamster = treats / hamsters;
    boolean enoughTreats = treatsPerHamster >= neededTreats;        

    if (enoughTreats = true) {
        System.out.println("There are enough treats for all the hamsters!");
    }
    else if (enoughTreats = false) {
        System.out.println("Oh no! There aren't enough treats!");        
    }

}
}

为什么这个程序返回有人能向我解释，有足够的对待所有的仓鼠！无论neededTreats>treatsPerHamster？

Can someone explain to me why this program returns "There are enough treats for all the hamsters!" regardless of whether "neededTreats" > "treatsPerHamster"?

感谢您。

推荐答案

您指定值true以enoughtreats。

You are assigning the value true to enoughtreats.

尝试使用等于运算符，而不是分配：

Try using the equality operator rather than assignment:

if (enoughtreats == true) {
...
}

或者只是：

if(enoughtreats) {
...
}
