E4.17 Write a program that reads two times in military format (0900, 1730) and prints the number of hours and minutes between the two times. Here is a sample run. User input is in color. Please enter the first time: 0900 Please enter the second time: 1730 8 hours 30 minutes Also, deal with the case where the first time is later than the second: Please enter the first time: 1730 Please enter the second time: 0900 15 hours 30 minutes E5.19 Write a program that takes user input describing a playing card in the following shorthand notation: A Ace 2 ... 10 Card values J Jack Q Queen King D Diamonds H Hearts S Spades Clubs Your program should print the full description of the card. For example, Enter the card notation: QS Queen of Spades Implement a class Card whose constructor takes the card notation string and whose getDescription method returns a description of the card. If the notation string is not in the correct format, the getDescription method should return the string "Unknown". P6.5 Prime numbers. Write a program that prompts the user for an integer and then prints out all prime numbers up to that integer. For example, when the user enters 20, the program should print 2 3 5 7 11 13 17 19 Recall that a number is a prime number if it is not divisible by any number except 1 and itself. The modulus operator in Java is the percent character (%) i.e (n%10 means modulus 10, for n=12345, 12345%10 means remainder when 12345/10 which would be 5) Use a class PrimeGenerator that gets the user input through the constructor with methods nextPrime and is Prime. The method isPrime returns true if the entered number is a prime. The method nextPrime return the next prime leading up to the input. The P6_5 class, has a main method that reads a positive integer as user input, constructs a PrimeGenerator object, and prints the primes
