remove substring in a string without using regex (cannot use replaceAll)

Question

I need to remove some substrings in strings (in a large dataset). The substrings often contain special characters, like these: ., ^, /,... and replaceAll() would treat them as s

Answer 1

There are 2 methods named replace in the String class that perform replacement without treating their parameters as regular expressions.

One replace method replaces one char with another char.

The other replace method replaces a CharSequence (usually a String) with another CharSequence.

Quoting the Javadocs from the second replace method:

Replaces each substring of this string that matches the literal target sequence with the specified literal replacement sequence.
