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
