# Java-Programming
This repository contains programs in the Java programming language.

# About Java Programming
--> Java is a widely-used, high-level, object-oriented programming language.
--> Known for its platform independence, which allows programs to run on any platform with a Java Virtual Machine (JVM).
--> Originally developed by James Gosling at Sun Microsystems (now owned by Oracle Corporation).
--> Java code is typically written in text files with a .java extension.
---
# Mode of Execution Used: 
Visual Studio Code
--> Visit the official website:
--> Download according to the platform that will be used like Linux, Macos or Windows.
--> Follow the setup wizard.
--> Create a new file with the extention of .java and then this file can be executed using java.
Java
--> Visit the official website of Java: https://www.java.com/en/
--> Download according to the platform that is going to be used.
--> After downloading, load the executble file and follow along the process.
Java Developement Kit
--> Visit the official website of Oracle: https://www.java.com/en/](https://www.oracle.com/java/technologies/downloads/
--> Download according to the platform that is going to be used.
--> After downloading, load the executable file and follow along the process.
---
# Executing Java Code
--> Open the command prompt in the working directory of java code file.
--> First the java code file is executed using java compiler with the following command:-
```
javac java-codefile.java
```
where java-codefile.java is the name of java code file. Make sure the name of class and code file is same else it gives error.
--> Now if this will run successfully a class file with the same name as code file will be saved in the directory.
--> Now run the following command to get output :-
```
java java-codefile
```
where java-codefile.java is the name of java code file. Also we do not need to mention extention here.

# Java Programming Features
- Strongly typed and statically compiled language.
- Automatic memory management via garbage collection.
- Rich standard library and extensive ecosystem of libraries and frameworks.
- Multi-threading support for concurrent programming.
- Exception handling for robust error management.
- Object-oriented principles like inheritance and polymorphism.
--> **Syntax and Structure**
- Java programs consist of classes.
- A class defines data (fields/variables) and methods (functions).
- The `public static void main(String[] args)` method is the entry point for execution.
- Statements end with a semicolon (`;`).
--> **Data Types**
- Primitive data types: `int`, `double`, `char`, `boolean`, etc.
- Reference data types: `String`, arrays, user-defined classes.
--> **Control Structures**
- `if`, `else if`, and `else` for conditional branching.
- `for`, `while`, and `do-while` for loops.
- `switch` for multi-branch decision-making.
--> **Object-Oriented Programming**
- Classes and objects for code organization.
- Inheritance, encapsulation, and polymorphism principles.
- Constructors and destructors.
--> **Exception Handling**
- `try`, `catch`, `finally` blocks for error handling.
- Throwing and catching exceptions.
--> **Garbage Collection**
- Automatic memory management for freeing unused objects.
- Helps prevent memory leaks leading to better memory management.
--> **Platform Independence**
- Compiled Java bytecode runs on any platform with a compatible JVM(Java Virtual Machine).
- This makes java a platform independent programming languge.
