Answer to Question #295702 in Java | JSP | JSF for bob

Question

Java Code please Input The first line contains an integer which is either 1 or 2. If it is a 1, it means to create a Date via the default constructor. If it is a 2, 3 integers follow in the next line representing the day, month, and year of the Date to be created. This is then followed by a number m representing the number of operations to be performed followed by the operations themselves as specified below: 1 - setDay 2 - setMonth 3 - setYear 4 - setDate 5 - getDay 6 - getMonth 7 - getYear 8 - toString 9 - dayOfTheWeek For operations 1, 2, 3, one integer follows. For setDate, 3 integers follow (D M Y). For the rest of the operations, no other inputs follow.
