Object and classes

Objects are instances of classes, which serve as blueprints or templates for creating objects. Classes define the structure and behavior of objects, encapsulating their data (attributes) and methods (functions). Java follows an object-oriented programming paradigm, where objects are the building blocks used to model and interact with data and functionality in the software. It allows for modular, reusable, and organized code, making it a fundamental concept in Java programming.

  1. Use of object
  2. Creation of object and its type
  3. Top level class
  4. Inner class
    1. Static classes
    2. Non static classes
    3. Local classes
    4. Anonymous classes
  5. Constructor
    1. Constructor overloading
    2. Constructor chaining
  6. Method
    1. Method overloading
    2. Method overriding

Control statement

Control statements in Java are essential for making decisions and controlling program flow. They include "if" for conditional branching, "for" and "while" loops for iteration, and "switch" for multiple branching.

  1. Branching  / Selection (if, if-else, else-if, switch)
  2. Iteration / looping (for,  while, do-while)
  3. Jumping (return, break, continue)

Array

Arrays in Java are used to store multiple values of the same type. They provide a structured way to manage and manipulate data, making them fundamental for efficient data handling in Java.

  1. Single dimension
  2. Multi dimension

Inheritance

Inheritance in Java is a mechanism where a new class can inherit properties and behaviors from an existing class. It promotes code reusability and hierarchical structuring of classes.

  1. Single level
  2. Multi level
  3. Hierarchical

Keyword

Keywords in Java are reserved words with special meanings and predefined functionality within the programming language. They cannot be used as identifiers or variable names.

  1. Some special keyword
    1. This keyword
    2. Super keyword
    3. Final keyword
    4. Static keyword
    5. Abstract keyword
  2. Access specifier
    1. Default
    2. Public
    3. Private
    4. Protected

Interface and Abstract class

Java course in Vizag, we explore two crucial concepts: Interfaces and Abstract Classes. An interface defines a contract that classes must implement, enabling multiple inheritance and ensuring consistent behaviors. Abstract classes provide a blueprint for subclasses but can't be instantiated themselves. Both are vital in achieving code modularity and flexibility in Java development. Understanding these concepts is fundamental for building robust, extensible Java applications.

String Handling

String handling in our Java course covers manipulating and processing text data. We delve into creating, modifying, and searching strings, a fundamental skill for Java developers.

  1. String class(Immutable class)
    1. Different way of string object creation
    2. Memory allocation of string.
    3. Heap memory
    4. Global  heap memory
    5. Static memory
  2. StringBuffer class(Mutable class) / StringBuilder class
  3. StringTokenizer class

Exception Handling

Exception handling in Java is vital for managing errors during program execution. We teach students to handle and recover from exceptions to ensure robust and reliable Java applications. In our blog, you will find the different types of exceptions in Java, including checked and unchecked exceptions, as well as how to use try-catch blocks to manage

Threading

Threading in Java allows concurrent execution of tasks, enhancing performance and responsiveness. Our Java course covers thread creation, synchronization, and management, enabling students to build efficient multi-threaded applications.

  1. What is Multitasking?
  2. What is the process?
  3. What is the thread?
  4. What is the multithreading?
  5. Thread life cycle
  6. Thread synchronization

IO Stream

IO (Input/Output) Streams in Java are used for reading and writing data. Our Java course covers working with various streams to efficiently handle data input and output operations in Java applications.

  1. Byte Stream
  2. Character Stream
  3. Serialization and de-serialization
  4. Externalization (serialize a static object/variable)

Collection API

Java Collections API provides a framework for working with groups of objects, such as lists, sets, and maps. It includes interfaces and classes like List, Set, Map, and various utility classes for data manipulation. This API simplifies data storage and manipulation, enhancing the efficiency and versatility of Java programs.

Reflection API (Dynamic class loading)

Reflection API in Java allows for dynamic class loading and runtime examination of class attributes and behaviors. It enables access to class information, methods, fields, and constructors at runtime, making it possible to create, inspect, and modify classes dynamically. This is useful for tasks like dependency injection and plugins.

TCP/IP and Socket Programming

TCP/IP is a foundational protocol suite for internet communication. In Java, socket programming uses TCP/IP to establish network connections. Sockets are endpoints for data exchange between devices over a network. Java's java.net package provides classes for creating sockets and managing network communication. Developers can create server and client applications that utilize sockets to send and receive data, enabling efficient, reliable, and platform-independent network communication. This is crucial for various networked applications, such as web servers, chat applications, and remote data transfer systems.

Lambda Expression

Lambda expressions in Java are concise, anonymous functions that enable the representation of functional interfaces using a more compact syntax. They simplify code by reducing boilerplate, especially when working with collections or functional programming constructs. Lambdas are particularly useful in the context of Java's Stream API for efficient data manipulation. They enhance code readability and maintainability by encapsulating behavior as a method argument, promoting functional programming paradigms.

Packages

Packages in Java are a way to organize classes and interfaces. They provide a hierarchical structure, preventing naming conflicts and simplifying code management. Packages help maintain code modularity and reusability.

Object-Oriented Programming

Object-Oriented Programming (OOP) in Java is a programming paradigm that uses classes and objects to model and structure code. It promotes encapsulation, inheritance, and polymorphism for creating modular, reusable, and organized software.
