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
