Java Generics: Java generic classes and generic methods allow the programmers to specify, with a single class declaration, a set of related types and with a single method declaration, a set of related methods. Using the concept of generics, user can write a generic method sort for sorting objects array then call this method with String arrays, Integer arrays, Double arrays and more for sorting the elements of the array. The user can create a single generic method and call it with arguments of different types. The compiler handles the methods calls appropriately based on the types of arguments passed to the generic method. Java Collection: A framework which provides architecture to store and manipulate a set of objects is called as Java collection. Java collection is a single set of objects. It provides interfaces like, “List”, “Set”, “Queue”, “Deque” and the classes like, “ Vector ”, “ArrayList”, “LinkedList” and so on.

Program Plan Intro

Java Generics:

Java generic classes and generic methods allow the programmers to specify, with a single class declaration, a set of related types and with a single method declaration, a set of related methods.

Using the concept of generics, user can write a generic method sort for sorting objects array then call this method with String arrays, Integer arrays, Double arrays and more for sorting the elements of the array.

The user can create a single generic method and call it with arguments of different types.

The compiler handles the methods calls appropriately based on the types of arguments passed to the generic method.

Java Collection:

A framework which provides architecture to store and manipulate a set of objects is called as Java collection.

Java collection is a single set of objects.

It provides interfaces like, “List”, “Set”, “Queue”, “Deque” and the classes like, “Vector”, “ArrayList”, “LinkedList” and so on.

Modular Program Structure. Analysis of Structured Programming Examples. Ways to Reduce Coupling. Based on the given problem, create an algorithm and a block diagram, and write the program code: Function: y=xsin⁡x Interval: [0,π] Requirements: Create a graph of the function. Show the coordinates (x and y). Choose your own scale and show it in the block diagram. Create a block diagram based on the algorithm. Write the program code in Python. Requirements: Each step in the block diagram must be clearly shown. The graph of the function must be drawn and saved (in PNG format). Write the code in a modular way (functions and the main part should be separate). Please explain and describe the results in detail.
