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.
