“Java foundation classic procedure 100 cases” (01) judge leap year

Small knowledge, big challenge! This article is participating in the creation activity of “Essential Tips for Programmers”

Leap years are judged by the following rules:

(1) A year that is divisible by 4 but not by 100 is a leap year.

(2) If a year is divisible by 400, it is a leap year.

package csdncom.tt;

import java.util.Scanner;

/** * Created by Administrator on 2021/10/30. */
public class LeapYear {
	public static boolean isLeapYear(int year) {
		return ((year % 4= =0 && year % 100! =0) || year % 400= =0);
	}

	/ * * *@param args
	 */
	public static void main(String[] args) {
		System.out.print("Please enter the year to query [integer]:");

		Scanner input = new Scanner(System.in);

		int year;
        // Get keyboard input
		if (input.hasNextInt()) {
			year = input.nextInt();
		} else {
			System.out.println("Input data format is not correct!");
			System.exit(0);
		}
		if (isLeapYear(2000)) {
			System.out.println(It's a leap year.);
		} else {
			System.out.println("Not a leap year."); }}}Copy the code
