求两数之和

import java.util.Scanner；

public class tt {public static void main(String[] args) {int number1 = (int) (System.currentTimeMillis() % 100);int number2 = (int) (Math.random() * 100);Scanner input = new Scanner(System.in);System.out.print("What is " + number1 + "+" + number2 + "?");int answer = input.nextInt();System.out.println(number1 + " + " + number2 + " = " + answer + " is "+ (number1 + number2 == answer));}}

随机取2个在100内的数求和

import java.util.Scanner;public class tt {public static void main(String[] args) {int radius=10;Scanner input = new Scanner(System.in);int pointx=input.nextInt();int pointy =input.nextInt();int s=pointx*pointx+pointy*pointy;if(Math.sqrt(s)<radius)System.out.println("inside the circle");else if(Math.sqrt(s)==10)System.out.println("on the circle");else System.out.println("outside the circle");}}

求点是否在圆内
