Scanner class methods in Java Part -I

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.

close(): This method closes this scanner.

delimiter(): This method returns the Pattern this Scanner is currently using to match delimiters.

equals(Object): This method indicates whether some other object is "equal to" this one.

findAll(Pattern): This method returns a stream of match results from this scanner.

findAll(String): This method returns a stream of match results that match the provided pattern string.

findInLine(Pattern): This method attempts to find the next occurrence of the specified pattern ignoring delimiters.

findInLine(String): This method attempts to find the next occurrence of a pattern constructed from the specified string, ignoring delimiters.

findWithinHorizon(Pattern, int): This method attempts to find the next occurrence of the specified pattern.

findWithinHorizon(String, int): This method attempts to find the next occurrence of a pattern constructed from the specified string, ignoring delimiters.

forEachRemaining(Consumer): This method performs the given action for each remaining element until all elements have been processed or the action throws an exception.

hashCode(): This method returns a hash code value for the object.

hasNext(): This method returns true if this scanner has another token in its input.

hasNext(Pattern): This method returns true if the next complete token matches the specified pattern.

hasNext(String): This method returns true if the next token matches the pattern constructed from the specified string.

hasNextBigDecimal(): This method returns true if the next token in this scanner's input can be interpreted as a BigDecimal.

hasNextBigInteger(): This method returns true if the next token in this scanner's input can be interpreted as a BigInteger in the default radix.

hasNextBigInteger(int): This method returns true if the next token in this scanner's input can be interpreted as a BigInteger in the specified radix.

hasNextBoolean(): This method returns true if the next token in this scanner's input can be interpreted as a boolean value using a case insensitive pattern created from the string "true|false".

hasNextByte(): This method returns true if the next token in this scanner's input can be interpreted as a byte value in the default radix.

hasNextByte(int): This method returns true if the next token in this scanner's input can be interpreted as a byte value in the specified radix.
