The replaceAll() method in Java is used to replace parts of a string using a regular expression.

The replaceAll() method in Java is used to replace parts of a string using a regular expression.

Note that in most languages, including Java, the String object is immutable. In other words, you can't change it. If you want a slightly different string value then you have to create a second object. For that reason, replaceAll() does not actually change the string being searched, but rather returns a new string that is the result of the specified search and replace actions.
