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!"); } } }
谁能解释一下为什么这个程序会返回有足够的零食给所有的仓鼠!"不管是否neededTreats">treatsPerHamster"?
Can someone explain to me why this program returns "There are enough treats for all the hamsters!" regardless of whether "neededTreats" > "treatsPerHamster"?
谢谢.
推荐答案
您正在将值 true 分配给 enoughtreats.
You are assigning the value true to enoughtreats.
尝试使用相等运算符而不是赋值:
Try using the equality operator rather than assignment:
if (enoughtreats == true) { ... }
或者简单地说:
if(enoughtreats) { ... }
