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

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

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

1. **Introduction to Regex in Java**: An overview of regular expressions and their essential role in pattern matching and text manipulation.
2. **Objective**: Understand the concept of capturing groups in regex and why defining multiple groups can enhance text processing capabilities.
3. **Defining Multiple Groups**: Step-by-step guide on how to define multiple capturing groups within a regex pattern in Java.
4. **Regex Components**: Explanation of regex components used to create capturing groups, including parentheses `( )` for grouping multiple parts of a pattern.
5. **Implementing in Java**: Practical demonstration of integrating the regex pattern with multiple groups using the `Pattern` and `Matcher` classes in Java.
6. **Accessing Captured Groups**: How to access and utilize the content captured by each group in Java regex matches.
7. **Testing and Validation**: Best practices for testing the regex pattern with various input texts to verify correct grouping and capturing behavior of multiple groups.
8. **Practical Examples**: Real-world examples showcasing scenarios where multiple capturing groups are beneficial, such as extracting structured data, parsing complex strings, and performing data validation.
9. **Optimization Tips**: Tips for optimizing regex patterns with multiple groups for improved performance 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.

**Why Learn about Multiple Groups in Java Regex:**
Mastering the creation and use of multiple capturing groups in regex is essential for developers handling text parsing, data extraction, and content analysis tasks.

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