java练习--随机数加法器

问题及代码：

问题描述：

随机生成两个小于100的整数，计算并输入这两个数的结果，如果结果正确，就输出“You are correct!",如果错误就自动输出正确答案；

程序代码：

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

}

运行结果：
