replace() function allows you to replace all instances of a given character with another character. You can also use
replace to replace substrings of a String with a different substring.
There is no circuit for this example, though your board must be connected to your computer via USB and the serial monitor window of the Arduino Software (IDE) should be open.
Caution: If you try to replace a substring that's more than the whole String itself, nothing will be replaced. For example:
String stringOne = "<html><head><body>"; String stringTwo = stringOne.replace("<html><head></head><body></body></html>", "Blah");
In this case, the code will compile, but
stringOne will remain unchanged, since the replacement substring is more than the String itself.
