学习Java而编写的猜数字的程序代码。

/** *  */package org.literal.test;import java.util.Scanner;/** * @author literal kernel * */public class Main {    /**     * @param args     */    public static void main(String[] args) {        // TODO 自动生成的方法存根        Scanner input = new Scanner(System.in);        // generate random number        int num = (int) (Math.random() * 100.0);                int guess;        do        {            System.out.println("请猜测：");            guess = input.nextInt();            if(guess < num)            {                System.out.println("小了");            }            if(guess>num)            {                System.out.println("大了");            }        }while(guess != num);                // guess it!        System.out.println("猜对了！");                input.close();    }}
