String.replace

Syntax:: String.replace(string, oldSubString, newSubString)
string: The mandatory string parameter can be any string containing one or more of any combination of characters and white spaces.
oldSubString: The mandatory oldSubString parameter can be any string containing one or more of any combination of characters and white spaces.
newSubString: The mandatory newSubString parameter can be any string containing zero or more of any combination of characters and white spaces. This parameter can also be the empty string.

Replaces all occurrences of a substring with a new substring.

The String.replace function searches the given string, removes each occurrence of the designated old substring, replaces each occurrence with a designated new substring, and returns the modified string.

You can use the String.replaceAt function to replace a specified element in a string with a new substring (new element). The String.subString function can be used to return a substring out of a given string.
