Leap year or not in java.

  Formula to calculate leap year. Identify the year we want to know if its a leap year. We then divide the year by 4 to check if its evenly divisible. Then confirm that the year is not evenly divisible by 100. Check if the year is divisible by 400. If the year is evenly divisible by 4, then the year is a leap year. If the year is only evenly divisible by 100 and not evenly divisible by 400, then the year is not a leap year. package com.company ; import java.util.Scanner ; public class Main { public static void main ( String [] args ) { // write your code here int year ; Scanner sc = new Scanner ( System . in ); System . out . print ( "Enter year : " ); year = sc . nextInt (); if (( year % 4 == 0 ) && ( year % 100 != 0 ) && ( year % 400 != 0 )) { System . out . println ( year + " is Leap Year" ); } else { System . out . println ( year + " is Not L

Number is even or odd in java

  package com.company ; import java.util.Scanner ; public class Main { public static void main ( String [] args ) { // write your code here int a ; System . out . println ( "Enter a number : " ); Scanner sc = new Scanner ( System . in ); a = sc . nextInt (); if ( a % 2 == 0 ) { System . out . println ( "Even number" ); } System . out . println ( "Odd number" ); } } Enter a number : 23 Odd number Process finished with exit code 0
