JAVA LAB PROGRAM ALGORITHM:

1. Develop a Java package with simple Stack and Queue classes.  Use JavaDoc comments for documentation

ALGORITHM:

step 1:Define package pack1 with the keyword package.

step 2:Define the class ArrayQueue with the integers.

step 3:Using a 1 argument constructor,the max size of the queue is assigned.

step 4:Define the method insert() with an item in object type as argument to insert an item.

step 5:Define the method remove() to delete an item from the queue.

step 6:Define the method peek() to return the item which is at the top of stack.

Step 7:Define the method displayAll() to display the contents of the queue.

step 8:Terminate the class .Create an another package pack1 using the keyword package.

step 9:Define the class ArrayStack with an object array'a' and an integer top as datamembers.

step 10:Using a one argument constructor define the size of the array.

step 11:Define the method push() to push an item into the stack.

step 12:Define the method pop() to delete an item from the stack.

step 13:Define the method peek() to return the item at the top of the stack.

step 14:Terminate the class.

step 15:Import the package pack1,define the class StackQueueDemo.

step 16:Define the main() in the class.

Create objects for the classes ArrayStack and ArrayQueue and access the methods using the objects.

step 17:Display the result.

step 18: terminte the main() and terminate the class.

2. Design a Date class similar to the one provided in the java.util package

ALGORITHM

step 1:Define the class MyDate with members date,month,year,hour,min,sec.

step 2:USing a default constructor,set the values using the predefined Dateclass.

step 3:use parameterised constructors to set the values for the members.

step 4:Define the methods getYear(),getMonth(),getDate(),  to return the year,month,date .

step 5:Define the methods setYear(),setMonth(),setDate. to set the values for year,month,date,.

step 6:Define the method after() with the return type boolean to check whether the given date is after the current date.

step 7:Define the method before() with the return type boolean to check whether the given date is before the current date.

step 8:Define the method compareTo() with the return type integer to compare two dates.it will return 0 if both are same,will return 1 if date is after currrent date else it returns -1.

step 9:terminate the class.

step 10:Define the datetest and define the main() in it.

step 11:Create many objects for the class MyDate and access the methods of the class using different objects.

step 12:Display the result.

step 13:terminate the main() and class.
