charAt()
The charAt(int index) method returns a single character
at the specified index.
If the index is negative, or greater than length()-1,
an IndexOutOfBoundsException
is thrown (and for now your program stops running).
The value returned by charAt(int index) is a char,
not a String containing a single character.
A char is a primitive data type,
consisting of two bytes that encode a single character.
| Expression | Result |
|---|---|
String source = "Subscription"; | "Subscription" |
source.charAt(0) | 'S' |
source.charAt(1) | 'u' |
source.charAt(5) | 'r' |
source.charAt(source.length()-1) | 'n' |
source.charAt(12) | IndexOutOfBoundsException |
What is wrong with the following fragment:
char oneD = new char( 'D' ); System.out.println( oneC.length() );
