Core Java

Java is a general purpose very powerful computer programming language. It is concurrent, class-based, and object-oriented designed to have few implementation dependencies. Java was specially designed to have a look and feel of C++ language. It is an object-oriented programming model which is simpler to use than C++.

Java is basically used to create applications which can run on a single computer or can be distributed among servers and clients in a network. The developers used this programming language to create applications on your computer. Java even consists of a web plug-in which allows you to run the applications in your browser.

This powerful language is now used by millions to play games, chat, perform online calculations, and to view 3D images. We at Saksham, provide you with flexible, easy to understand and affordable Core Java Training. Our training helps individual to understand the in-depth concepts of this programming language. The training program comprises of classes based on the current and updated requirements of IT Industry. With an extensive industry experience, our instructors provide proper guidance to those willing to fetch IT jobs.  They trained students to become expert and leaders of programming using Java.


Course Overview

Java is a popular high-level, object-oriented programming language that was developed by Sun Microsystems (now owned by Oracle Corporation) in the mid-1990s.
  • History of Java
  • features of Java
  • JVM (Java Virtual Machine)
  • JDK (Java Development Kit)
  • basic Java program structure.
Variables, data types, and operators are fundamental concepts in Java that form the building blocks of any program.
  • Primitive data types
  • Reference types
  • Variables
  • Literals
  • Type casting
  • Arithmetic operators
  • Relational operators
  • Logical operators
  • Assignment operators
Control flow statements in Java provide mechanisms for controlling the execution flow of a program.
  • If-else statements
  • Switch statements
  • For loops
  • While loops
  • Do-while loops
  • Break and continue statements.
Object-Oriented Programming (OOP) is a programming paradigm that organizes code around objects, which are instances of classes.
  • Classes
  • Objects
  • Constructors
  • Encapsulation
  • Inheritance
  • Polymorphism
  • Abstraction.
Methods and parameters are essential components of Java programming that allow you to organize and encapsulate code for reusability and modularity.
  • Method declaration
  • Return types
  • Method overloading, method overriding, passing parameters, and variable scope.
  • Method overriding
  • Passing parameters
  • variable scope.
An array is a fixed-size, ordered collection of elements of the same data type. A string is an object that represents a sequence of characters.
  • Single-dimensional arrays
  • Multidimensional arrays
  • Array manipulation
  • Strings
  • String manipulation
  • String comparison.
Exception handling is a crucial aspect of Java programming that allows you to handle and manage errors and unexpected situations that can occur during program execution.
  • Try-catch blocks
  • Handling exceptions
  • Throwing exceptions
  • Checked and unchecked exceptions
  • Finally block.
Java Class Library or Java API (Application Programming Interface), is a collection of pre-built classes and interfaces provided by Oracle as part of the Java Development Kit (JDK).
  • Java Standard Library classes
  • Methods from packages
  • Such as java.lang, java.util, and java.io.
  • Java.util
  • Java.io.
File I/O (Input/Output) refers to the process of reading data from and writing data to files in a computer system using the core Java programming language.
  • Reading from and writing to files using classes
  • FileReader
  • FileWriter
  • BufferedReader
  • BufferedWriter.
Generics in core Java provide a way to create reusable code that can work with different types while ensuring type safety at compile time.
  • Introduction to generics
  • Parameterized classes
  • Parameterized methods
  • Generic collections.
The framework includes a set of core interfaces that define common collection types and behaviors.
  • Introduction to collections
  • List
  • Set
  • Queue
  • Map
  • Iterators
  • Sorting
  • Searching.
Multithreading is a core concept in Java that allows multiple threads of execution to run concurrently within a single program.
  • Introduction to threads, creating and running threads, thread synchronization, and thread communication.
  • Creating and running threads
  • Thread synchronization
  • Thread communication.
Inner classes offer several benefits, including encapsulation, code organization, and improved code readability.
  • Nested classes,
  • Static nested classes
  • Inner classes
  • Anonymous inner classes.
Serialization in core Java refers to the process of converting an object into a byte stream, which can be saved to a file, sent over a network, or stored in a database.
  • Byte streams
  • Character streams
  • Serialization
  • Deserialization.
JDBC (Java Database Connectivity) is a core Java API that provides a standard way for Java applications to interact with relational databases.
  • Introduction to JDBC
  • Connecting to databases
  • Executing queries
  • Handling result sets.
Java provides the Swing and JavaFX frameworks as part of the core Java libraries to create GUI applications.
  • Basics of GUI programming using Java Swing
  • JavaFX
  • Creating windows
  • Buttons
  • Event handling
  • Layouts.
Java Annotations in core Java provide a way to add metadata and additional information to Java code elements, such as classes, methods, fields, and parameters.
  • Understanding annotations
  • Creating custom annotations
  • Using built-in annotations.
Java is a powerful and versatile programming language known for its simplicity, portability, and robustness.
  • Lambda expressions,
  • Functional interfaces
  • Streams
  • Default methods.
