File Reading:

You are required to write Java code that reads a text file.

Implement a method to count the number of lines in the file.

Develop another method to count the number of words in the file.

Create a third method to count the number of characters in the file.

Ensure your code is efficient and can handle files of varying sizes.

Implement a feature to calculate the average word length in the file.

Add a function to search for specific words or phrases in the file and display their occurrences.

Random File Generation:

In addition to file reading, you must create a random file programmatically.

The random file should contain content generated by your code, not manually entered text.

The content can be random text, numbers, or any creative content of your choice. Make it interesting!

Ensure that the generated file is in a readable format and does not contain any errors.
