Java Tutorial
A Complete Introduction
for Beginners
What is Java?
Java is a high-level, object-oriented
programming language.
It is platform-independent due to
its "write once, run anywhere"
capability.
Widely used for desktop
applications, mobile apps,
enterprise software, and web
applications.
Features of Java
Platform-
independent
Supports
multithreading
Simple and easy
to understand
Secure and robust
Distributed and
portable
Object-oriented
programming language
Java Editions
Java Micro Edition (Java ME):
Java Standard Edition (Java SE):
JavaFX:
Java Enterprise Edition (Java EE):
Core features and libraries
For mobile and embedded devices For creating rich user interfaces
Tools for web and enterprise applications
Components of Java
JDK (Java Development Kit):
JRE (Java Runtime
Environment):
Executes Java
programs
Tools required to develop Java applications
Provides environment to run
Java applications
JVM (Java Virtual
Machine):
Java Syntax Overview
Java programs are structured using
classes and methods
Follows a clear and readable syntax
Supports variables, data types, and
operators
Uses semicolon-based statements
and block structures
Variables and Data Types
Java supports primitive and non-
primitive data types
Non-primitive types include
strings, arrays, and objects
Each data type has a fixed size and
purpose
Primitive types include number types,
text, and boolean types
Control Flow Statements
Decision-making:
Branching:
Looping:
break, continue
for, while, do-
while
These statements control the flow of program
execution
if, else, switch
File Handling in Java
Supports reading and writing data
to files
Useful for storing, retrieving, and
processing external data
Commonly used in data-driven
applications
Summary
Java is a versatile and powerful
programming language
Widely used in modern
software development
Offers strong OOP support and
platform independence
Learning Java builds a solid
foundation for IT careers
