//判断是否为奇数和偶数

import java.util.Scanner;

    public static void main(String[] args) {

        System.out.print("请输入一个数字：");

        Scanner i=new Scanner(System.in);

        int    num=i.nextInt();

        if (num<=0) {

            System.out.print("请输入正整数！");

        }else if (num%2==0) {

            System.out.print("“"+num+"”"+"为偶数！");

        }else {

            System.out.print("“"+num+"”"+"为奇数！");

        }
