Parameters

Old -- this is the old substring to be replaced.

New -- this is a new substring that replaces the old substring.

Max -- if the max value of this optional parameter is given, only the first count is replaced.

Return Value

This method returns the replace between the copy of the string and the old substring. If the maximum value of the optional parameter is specified, only the first count is replaced.

Example

The following example demonstrates the use of the replace () method.
