Question

鉴于此要求

创建一个创建随机数的代码，并要求用户进行2次猜测，然后打印出实际数字，并说明您猜测哪一个最接近

我被困在最后一部分。请帮忙。

import java.util.Scanner;

public class GuessNumber {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("I have picked a number between 1 to 100 try to guess it.");
        int randomNumber = (int) (Math.random() * 100 + 1);
        System.out.println("Enter Your First Guess.");
        int guess1;
        guess1 = sc.nextInt();
        System.out.println("Enter Your Second Guess.");
        int guess2;
        guess2 = sc.nextInt();
        System.out.println("The number was " + randomNumber);
        int range;
        range = randomNumber;



    }
}

Answer 1

使用Math.min（Math.abs（randomNumber-guess1），Math.abs（randomNumber-guess2））

Answer 2

做这样的事情：

//Calculate difference and use absolute value (turn negative values into positive if necessary)
int difference1 = Math.abs(randomNumber - guess1)
int difference2 = Math.abs(randomBumber - guess2)

//Compare result
if(difference1<difference2) {
    System.out.println("Guess1 was closer"); 
} else if (difference1>difference2) {
    System.out.println("Guess2 was closer"); 
} else {
    System.out.println("Both were equally close!"); 
}

有比此更短的方法，但是scince你是首发我认为这是一种易于理解且易于使用的方式。
