Welcome to java course
Here's a basic introduction to Java:
What is Java?
Java is a high-level, object-oriented programming language developed by Sun Microsystems (now owned by Oracle Corporation).
Key Features:
1. *Platform Independent*: Java code can run on any platform that has a Java Virtual Machine (JVM) installed.
2. *Object-Oriented*: Java is based on the principles of object-oriented programming (OOP).
3. *Simple and Familiar Syntax*: Java's syntax is based on C++ and is easy to learn.
4. *Robust Security*: Java has built-in security features to protect against data corruption and unauthorized access.
Basic Java Concepts:
1. *Variables*: Store and manipulate data.
2. *Data Types*: Define the type of data a variable can hold (e.g., int, double, String).
3. *Operators*: Perform arithmetic, comparison, and logical operations.
4. *Control Structures*: Control the flow of a program (e.g., if-else statements, loops).
5. *Methods*: Blocks of code that perform a specific task.
Java Applications:
1. *Android Apps*: Java is used to develop Android apps.
2. *Web Applications*: Java is used to develop web applications using frameworks like Spring and Hibernate.
3. *Desktop Applications*: Java is used to develop desktop applications like IDEs and games.
4. *Enterprise Software*: Java is used to develop enterprise software for large organizations.
Basic Java Example:
```
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
```
This code prints "Hello, World!" to the console.
Java is a popular and versatile programming language with a wide range of applications!
