學習使用if-else和while迴圈

程式碼：

import java.util.Scanner;
import java.util.Random;
public class T3{
    public static void main(String args[]){
        Scanner reader = new Scanner(System.in);
        Random random = new Random();
        System.out.println("給你一個1至100之間的整數,請猜測這個數");
        int realNumber = random.nextInt(100)+1;
        int yourGuess = 0;
        System.out.print("輸入您的猜測:");
        yourGuess = reader.nextInt();
        while(yourGuess!=realNumber){
            if(yourGuess>realNumber){
                System.out.print("猜大了,再輸入你的猜測:");
                yourGuess = reader.nextInt();
            }
            else if(yourGuess<realNumber){
                System.out.print("猜小了,再輸入你的猜測:");
                yourGuess = reader.nextInt();
            }
        }
        System.out.println("你猜對了!");
    }
}
