Problem: Write a Java program that displays all the leap years, 10 per line, from 1001 to 2100, separated by exactly one space. Also display the total number of leap years in this period. Hints: you need to use a loop ( for-loop is more suitable)

Answer 1

//TestCode.java
public class TestCode {
    public static boolean isLeapYear(int userYear){
        if(userYear % 4 == 0 && userYear % 100 != 0){
            return true;
        }
        else if(userYear % 400 == 0){
            return true;
        }
        return false;
    }

    public static void main(String[] args) {
        int k = 1;
        for(int i = 1001;i<=2100;i++){
            if(k%10==0){
                System.out.println();
                k = 1;
            }
            if(isLeapYear(i)){
                System.out.print(i+" ");
                k++;
            }
        }
    }
}
