This course helps you to understand the concepts of object-oriented programming. The course covers introductory elements of object-oriented programming including inheritance, polymorphism, encapsulation, abstraction, aggregation and advanced concepts like error handling, file handling and Multi-threading.
Upon successful completion of the course, the learner will be able to
Provide class representation for the identified object
Select right data types for the member variables
Use appropriate control statements and operators to implement business rules
Handle exceptions with predefined and user-defined exceptions
Overload and override methods for polymorphism implementation
Compare and Contrast "Interfaces" and "abstract classes" and adopt using them on demand
Read and write from/into a file using IO API
Use Collections to store and manipulate data
Perform Multithreading operations
Store and retrieve data from MySQL database using JDBC concepts
Adhere to Java Coding standards
Model class diagram
Code using Three-layer architecture
Understand OOAD techniques
Welcome! In this module, you will be introduced to Classes and Objects which are the basic concepts of any Object-Oriented Programming language. You will be learning from modeling a real-time entity to create a programming model for real-world entities.
In real-world scenarios, we always work with a group of objects/data together. Collections framework in Java provides various data structures to use while enhancing the performance on the whole. In this module, you will be learning from a basic collection like the list to set, map and also learning how to implement them.
By this time you will be familiar with classes and objects. Any real-life entity would have a dependency or ownership over other such entities. Java helps you in modeling such relationships. In this module, you will be learning how to model a relationship between two classes/objects, the types of relationships.
Inheritance is a prime factor in Object-Oriented Programming which accounts for code reusability. Inheritance falls into the category of Is-A relationship. In this module, you will be learning inheritance and its types and also in the process, understanding where you must apply an inheritance paradigm in your application.
In this module, you will be learning about abstract classes and interfaces.These OO concepts are extension to inheritance, helping to model various design constraints into better implementations.
Exceptions are unwanted errors that interrupt the normal flow of execution. Exceptions & Errors are part and parcel of any application. Java provides a way to handle the exceptions and ensure smooth functioning of your applications.In this module, you'll be learning about exception and how to handle them.
Multithreading is a feature that enables concurrent execution of lightweight sub-processes. In current scenarios, need for the multi-threaded environment is increasing due to the enormous amount of data stored in any application.This module would focus on helping you to understand about creating a multi-threaded environment for an application and how to implement them.
Strings are important concepts for any programming language. There won't be any application without involving String manipulation. Several API methods are available in String class for easy implementation. In this module, you will be learning about String, StringBuffer and StringTokenizer, their differences and implementation.
In the earlier module, we learned about the collection, their types, and basic functionality. But that is not all about Java collections. Java has many more API methods for performing various functions in these collections. Also, there is comparator and comparable interfaces to define the ordering of these collections. This module will help you understand about comparator and comparable interfaces and implementation various nested collection objects for easy storage and retrieval of data.
In this module you will learn about the different streams and writers which are available in Java API. By now you would be familiar about BufferedReader and Scanner which is used to get console input. But there are many other stream readers and writes in java including reader and writer for files. File reading & writing forms an integral part of any application. From simple logging to storing Objects & Content, file processing plays a key role. Java has very well crafted API structure for File Processing.
In this module you will be learning about Annotations and Lambda expressions. Annotation is a form of syntactic metadata that can be added to Java source code used by Java compiler. Lambda expressions are similar to closures, in simple terms a kind of anonymous methods.
When you create applications, we may need to store data. Java Database Connectivity is very useful for connecting our Java application with various databases. It provides means to read, write and modify data in various databases like MySQL, MS SQL, etc.This module will help you in understanding about JDBC drivers, databases and various API methods to read/write data from database.
In this module, you will apply Java Object Oriented Programming concepts to solve complex real time case studies.
