Java

1. Java introduction

Before we start developing Java programs, we need to learn about who invented Java and how the language survived for nearly 27 years, its history and its basic features. This section of the course will introduce you to Java.

• History

• Features

2. Java Basics & Introduction to Eclipse

This section takes you to the post-installation phase of Java and introduces you to the most popular Java IDE, Eclipse. We will also discuss variables and arrays, datatypes, how to create packaged classes, and write your first Java code.

• Post-install configuration

• Compiling and executing

• Variables and arrays

• Create packaged classes

• Writing a simple program

• Data types

• Using Eclipse

• Eclipse shortcuts

3. Operators & Expressions

Operators in Java are the symbols that instruct the machine to perform an activity. These are mainly arithmetic, logical, binary, and boolean. This section clarifies the use of each operator in a statement or an expression. 

• Arithmetic operators

• Boolean operators

• Logical operators

• Binary operators

4. Control statements

Java uses decision-making statements and loops to control the execution of codes according to specific conditions. Here, you will learn about branching and iterative statements and understand what loops to use in Java and how they are functionally different. 

• Branching statements

• Iterative statements

• Break & Continue with enhancements

• While

• For

• Do..While

• Goto Statement

• Break and Continue statement

5. Java Object Oriented Programming

Java uses classes and objects in its programs, which is known as object-oriented programming. This section of the course will provide you with the basics of OOPs and ensure you understand the difference between class and object. In addition to that, you will learn a few more things that are essential when you are writing Java code, like reference variables, constructors and overloading constructors, member methods and overloading member methods, and so on.

• Basics of OOPs

• Fundamentals of class & object

• New keyword

• Reference variables

• Member methods of a class

• Constructors

• Finalize method

• Overloading member methods

• Overloading contractors

• Passing and returning objects with methods

• Access control

• Static methods

• Static variables

• Static block

• Using final keyword

• Unit testing using Junit-5

6. Inheritance

Java objects can inherit properties from their parent objects, and the concept of inheritance is an essential part of OOPs. If you know the implementation of inheritance in your codes, you can reuse methods from an existing class in your new classes, which is quite interesting. Here, you get a complete idea of inheritance, member accessibility, method overriding, preventing inheritance and some relevant topics. 

• Basics of inheritance

• Members accessibility in inheritance

• Using super keyword

• Multilevel inheritance

• The sequence of execution of constructors in inheritance

• Method overriding

• Dynamic method dispatch

• Abstract classes

• Preventing overriding

• Preventing inheritance

7. Exception handling

Exception handling in Java refers to handling runtime errors. Here, you will get to know what exceptions are and their types, as well as the use of try-and-catch keywords. There are a few predefined exceptions in Java, and you will know them in this section.

• Fundamentals of exceptions

• Types of exceptions

• Using try and catch keywords

• Multiple catches

• Nesting of try blocks

• Using throw keyword

• Using throws keyword

• Finally block

• Some predefined exceptions and their usage

• User defined exceptions

8. Interfaces

This part of the core Java course syllabus introduces you to Java interfaces, their purpose in a code, and how to implement them in a program.

• Purpose of interface

• Defining an interface

• Implementing interfaces

• Interface reference variables

• Interface with variables

• Extending interfaces

9. Multithreaded programming

Multithreaded programming refers to the execution of more than one part of a program to maximise the CPU’s memory usage. In this section, you will learn about the basics of threads and their model, defining threads, using multiple threads, and thread synchronisation. 

• Basics of threads

• Java threaded model

• Defining threads using Runnable interface

• Defining threads using Thread superclass

• Multiple threads

• Thread Priority values

• Thread Synchronization using synchronized methods 

• Thread Synchronization using synchronized blocks

10. Predefined Libraries

Java has multiple predefined libraries, which are basically codes of different classes that someone else wrote and help developers easily transform their ideas into coding. You will get to know some of the popular library classes during the course.

• Using String class

• Using java.lang package

• Working with Data & Time

• Utility framework

• Collection framework

• I/O framework
