问题及代码：

问题描述：

随机生成三个数，计算并输入这三个数的和，如果输入的正确则输出”You are correct!“，否则输出正确结果

程序代码：

import java.util.Scanner;
public class Que {
	public static void main(String[] args){
		int number1=(int)(Math.random()*100);
		int number2=(int)(Math.random()*100);
		int number3=(int)(Math.random()*100);
		System.out.println("What is "+number1+"+"+number2+"+"+number3+"?");
		Scanner input=new Scanner(System.in);
	    int answer=input.nextInt();
	    if (number1+number2+number3 == answer)
	    	System.out.println("You are correct !");
	    else
	    	System.out.println("You answer is wrong ! "+number1+number2+number3+" should be "+(number1+number2));
	}
