˃ The characters include letters, digits, punctuation marks, and nonprintable control characters such as the backspace, tab, carriage return, etc.

» Unicode

˃ The Unicode standard defines underlying numeric values for a huge set of 65,536 characters.

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
