Vrite a java program that reads from the command line (a year), then find whether a given year is a leap year or not. Hint. A year is said to be a leap year, if it is either divisible by 4 but not by 100 or divisible by 400.

I need help with this Java problem as it's explained in the image below:  Palindrome (Deque) A palindrome is a string that reads the same backwards and forwards. Use a deque to implement a program that tests whether a line of text is a palindrome. The program reads a line, then outputs whether the input is a palindrome or not.   Ex: If the input is: senile felines!   the output is: Yes, "senile felines!" is a palindrome.     Ex: If the input is: rotostor   the output is: No, "rotostor" is not a palindrome.   Ignore punctuation and spacing. Assume all alphabetic characters will be lowercase. Special case: A one-character string is a palindrome. Hint: The deque must be a Deque of Characters, but ordinary chars will be automatically converted to Characters when added to the deque.   Java Code:    import java.util.Scanner; import java.util.LinkedList; import java.util.Deque; public class LabProgram {       public static void main(String[] args) {         Scanner scnr = new…
