# CustomRegexMatcher
This Java program implements a custom regex matcher that checks whether a given input string matches a provided regular expression pattern. The program supports alphanumeric characters, period (.), and the asterisk (*) wildcard.
## Usage
1. **Compilation**:
- Make sure you have the Java Development Kit (JDK) installed on your computer.
- Open a terminal or command prompt.
- Navigate to the directory containing the `CustomRegexMatcher.java` file.
- Compile the Java code by running the following command:
```
javac CustomRegexMatcher.java
```
2. **Running the Program**:
- After successful compilation, run the program using the following command:
```
java CustomRegexMatcher
```
3. **Input Instructions**:
- The program will prompt you to enter the regular expression pattern. Enter the desired pattern and press Enter.
- Next, you'll be prompted to input the string you want to check against the regular expression. Enter the string and press Enter.
4. **View Results**:
- The program will process your inputs and display whether the input string matches the provided regular expression or not.
## Examples
Here are some example interactions when running the program:
```
Enter the regular expression:
a.b*
Enter the input string:
abbbc
The string matches the regular expression.
```
## Notes
- The program validates input parameters and handles edge cases according to the specified requirements.
- The matching logic includes recursive handling of the '*' wildcard.
- Feel free to customize the program, add more test cases, or modify the code as needed.
