I am supposed to read a text file via Java and blank out all the e-mail ids and URLs in the text file. This is to reduce noise in the data.
Are there any library functions in java to do the same?

You can read the file in using a FileInputStream and/or a BufferedReader. You can parse each line and use a regex to see if there are any matches for email or URL patterns, and create a new output string or stream to write them out.
Show us what you’ve tried and your current code.
As an addendum, I’ve used these:

With varying degrees of success.
