Replace characters in java string

Question

I am trying to replace the following text in some HTML:

[merchant]

I tried to use myString = myString.replace("\\[merchant\\]", "newText");

The string is not being replaced. Any ideas?

Answer 1

replace doesnt use a regular expression. Just use

myString = myString.replace("[merchant]", "newText");

Answer 2

Try this -

    String myString = "My Sampel String [merchant]. Another line with [merchant]";
    myString = myString.replace("[merchant]", "newText");

    System.out.println(myString);  

You don't have to use \\ here.

Answer 3

String#replace uses string literals, not regexes, so you shouldn't escape any special characters like [ or ]:

myString = myString.replace("[merchant]", "newText");
