A series of java programs intended for coding practices, concepts understanding and experiments. 

The repository will be updated with new try-outs and experiments regularly.

## Prerequisites

To run this project, you need the following:

- **Java Development Kit (JDK)**: Version 8 or higher is recommended.

- **Build Tool**: (Optional) Maven or Gradle, if you'd like to manage dependencies or structure.

- **IDE/Text Editor**: IntelliJ IDEA, Eclipse, or any other Java-supporting editor for easy code exploration.

- **Command Line**: To compile and run programs manually.

## Some of them covered are:

- **AdapterExample**: Demonstrates the Adapter Design Pattern for interface compatibility.

- **ComparatorExample**: Illustrates custom sorting using Java's `Comparator` interface.

- **DateAndTime**: Explores Java's Date and Time API, including `LocalDate` and `LocalTime`.

- **DecoratorExample**: Implements the Decorator Design Pattern for dynamic behavior addition.

- **GenericsExample**: Provides examples of using Java Generics in classes.

- **SingletonExample**: Covers the Singleton Design Pattern and ways to break and protect it.

- **StreamsExample**: Highlights Java 8 Streams API for functional-style operations on collections.

- **StringExamples**: Explores common string manipulation techniques.

- **TryCatchFinallyExample**: Demonstrates proper use of exception handling in Java.
