Design a class, pointType, that can store and process a point in the x-y plane. You should then perform operations on the point, such as showing the point, setting the coordinates of the point, printing the coordinates of the point, returning the x-coordinate, and returning the y-coordinate. Also, write a test program to test the various operations on the point.Need a java code Create a class called SingleItem This class represents a bag that can hold any single type of object (decided at bag-creation time), and only one item of that type at a time. You may have a zero-parameter constructor if you want one, but you must have the following three features: Add a method called (addItem()) which returns whether or not it was successfully added Add a method which removes an item from the bag and returns it (deleteAnItem()), return null if there is no item Add a method to check if an item is in the bag (hasAnIteminTheBag()) which returns true or false
