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.
