How to define nested multiple groups in a regular expression? | Java Regex | Regex in java

Welcome to our tutorial on **How to Define Nested Multiple Groups in a Regular Expression Using Java Regex**! In this video, you'll learn advanced techniques for leveraging regular expressions (regex) in Java to define and utilize nested multiple capturing groups effectively.

**In this video, we'll cover:**

1. **Introduction to Regex in Java**: An overview of regular expressions and their powerful capabilities in pattern matching and text manipulation.
2. **Objective**: Understand the concept of nested multiple capturing groups in regex and why they are useful for complex text processing tasks.
3. **Defining Nested Multiple Groups**: Step-by-step guide on how to define nested multiple capturing groups within a regex pattern in Java.
4. **Regex Components**: Explanation of regex components used to create nested multiple groups, including nested parentheses `( )` for hierarchical grouping.
5. **Implementing in Java**: Practical demonstration of integrating the regex pattern with nested multiple groups using the `Pattern` and `Matcher` classes in Java.
6. **Accessing Captured Groups**: Techniques for accessing and utilizing the content captured by each nested group in Java regex matches.
7. **Testing and Validation**: Best practices for testing the regex pattern with various input texts to ensure accurate grouping and capturing behavior of nested multiple groups.
8. **Practical Examples**: Real-world examples showcasing scenarios where nested multiple capturing groups are essential, such as parsing structured data, extracting specific information from complex strings, and performing data validation with hierarchical patterns.
9. **Optimization Tips**: Strategies for optimizing regex patterns with nested multiple groups for improved performance, maintainability, and scalability.
10. **Regex Flags**: Discussion on using regex flags in Java to modify pattern behavior, such as enabling case insensitivity or handling multiline input within nested groups.

**Why Learn about Nested Multiple Groups in Java Regex:**
Mastering the creation and use of nested multiple capturing groups in regex is crucial for developers working with intricate text parsing, data extraction, and content analysis requirements.

**Example Code:**
Throughout the tutorial, we'll provide advanced Java code examples demonstrating:
