1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

package com.liaojianya.chapter1;   import java.util.Scanner;   /**  * This program demonstrates the way of judge number is odd or even  * @author LIAO JIANYA  *  */ public class OddEven {     @SuppressWarnings("resource")     public static void main(String[] args)     {                   Scanner scan = new Scanner(System.in);         System.out.println("please input a number: ");         long read = scan.nextLong();         System.out.println("输入数据： " + read);                   if(read % 2 == 1 || read % 2 == -1)         {             System.out.println(read + " is odd");         }         else         {             System.out.println(read + " is even");         }                   System.out.println("the min_value of Long is: " + Long.MIN_VALUE);         System.out.println("the max_value of Long is: " + Long.MAX_VALUE);     } }
