Why Isn't My Java String Replacement Working?

Java String Replacement Not Working

The code snippet provided attempts to replace certain substrings within a string using the replace() method. However, the expected replacement does not occur.

The issue lies in the immutability of strings in Java. When the replace() method is called, it does not modify the original string reference. Instead, it returns a new string object with the replaced substrings. However, the code provided does not assign the returned string to the html variable.

To resolve this, assign the result of replace() to the html variable:

html = html.replace(delimiter + entry.getKey() + delimiter, entry.getValue());
Copy after login

By making this change, you ensure that the original html string is updated with the replaced substrings.
