String has a charAt method that returns the character at the specified position  Like arrays and Lists  String is 0-indexed  i e  the first character is at index 0 and the last character is at index length   - 1   So  assuming getSymbol   returns a String  to print the first character  you could do   System out println ld getSymbol   charAt 0       char at index 0
