• 判断一个数的奇偶性


    编写一个程序可以实现检测正负数的奇偶性。
    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);
    	}
    }

      正数运行结果1:

    please input a number: 
    12343252335
    输入数据: 12343252335
    12343252335 is odd
    the min_value of Long is: -9223372036854775808
    the max_value of Long is: 9223372036854775807

      负数运行结果2:

    please input a number: 
    -231441341
    输入数据: -231441341
    -231441341 is odd
    the min_value of Long is: -9223372036854775808
    the max_value of Long is: 9223372036854775807
