How to Write a Regex to Validate Image Names | Java Regex Tutorial | Regex in java

In this Java programming tutorial, learn how to create a regular expression (Regex) to validate image names effectively. Validating image names is essential for maintaining consistency and correctness in file management systems and applications. Using Regex in Java allows us to define specific rules for image name formats and ensure proper naming conventions are followed.

**Key Points Covered:**
- Introduction to regular expressions (Regex) and their role in Java.
- Understanding the typical structure and rules for image names.
- Step-by-step guide to crafting a Regex pattern for image name validation:
- Validating file extensions (e.g., .jpg, .png, .gif).
- Enforcing naming conventions (e.g., alphanumeric characters, underscores, dashes).
- Handling case sensitivity and special characters.
- Allowing or restricting specific patterns within image names.
- Implementing the Regex pattern using Java's `Pattern` and `Matcher` classes.
- Testing the image name validation Regex with various examples.
