Tips Simple String Methods » charAt() ˃ The charAt(index) method returns the character at a specific index in the string. ˃ The first character of a string is at index 0, the next at index 1, and so on. ˃ The index argument must be greater than or equal to 0, and less than the length of the string buffer. » replaceAll() ˃ The String class also contains the replaceAll method for replacing and splitting strings ˃ The replaceAll method replaces all matching substring. 32 https://www.facebook.com/Oxus20
