String indexOf() and lastIndexOf() Method

The String object indexOf() method gives you the ability to search for the first instance of a particular character value in a String. You can also look for the first instance of the character after a given offset. The lastIndexOf() method lets you do the same things from the end of a String.

equals 5, because the first
