Scanner class methods in Java Part -III

java.util.Scanner

A simple text scanner that can parse primitive types and strings using regular expressions.

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace.


Some methods of Scanner class.


nextByte(int)This method scans the next token of the input as a byte.


nextDouble()This method scans the next token of the input as a double.


nextFloat()This method scans the next token of the input as a float.


nextInt()This method scans the next token of the input as an int.


nextInt(int)This method scans the next token of the input as an int according to the specified radix.


nextLine()This method advances this scanner past the current line and returns the input that was skipped.


nextLong()This method scans the next token of the input as a long.


nextLong(int)This method scans the next token of the input as a long according to the specified radix.


nextShort()This method scans the next token of the input as a short.


nextShort(int)This method scans the next token of the input as a short according to the specified radix.

radix()This method returns this scanner's default radix.


remove()The remove operation is not supported by this implementation of Iterator.


reset()This method resets this scanner.


skip(Pattern)This method skips input that matches the specified pattern, ignoring delimiters.


skip(String)This method skips input that matches a pattern constructed from the specified string.


tokens()This method returns a stream of delimiter-separated tokens from this scanner.


toString()This method returns the string representation of this Scanner.


useDelimiter(Pattern)This method sets this scanner's delimiting pattern to the specified pattern.


useDelimiter(String)This method sets this scanner's delimiting pattern to a pattern constructed from the specified String.


useLocale(Locale)This method sets this scanner's locale to the specified locale.


useRadix(int)This method sets this scanner's default radix to the specified radix.
