Day4 闰年的计算

if-else的懒得写了

    import java.util.*;
    public class LeapYear {

            //scan

            System.out.println("please input a year:");
            int tempYear = scan.nextInt();
            System.out.print(tempYear + " is ");

            if(!isLeapYear(tempYear)){
                System.out.print("not ");
            }
            System.out.println("a leap year");
            
        }



        private static boolean isLeapYear(int paraYear) {
            if ((paraYear % 4 == 0 && paraYear % 100 != 0)||(paraYear % 400 == 0)) {
