public boolean hasNext()
Returns true if there is another token. May wait for a next token to enter the stream.
Throws:
IllegalStateException if the Scanner stream is closed.
public boolean nextBoolean()
Returns the next token as a boolean value, provided the next token is a well-formed string
representation of a boolean.
Throws:
NoSuchElementException if there are no more tokens.
InputMismatchException if the next token is not a well-formed string representation of a
boolean value.
IllegalStateException if the Scanner stream is closed.
public boolean hasNextBoolean()
Returns true if the next token is a well-formed string representation of a boolean value;
otherwise returns false.
Throws:
IllegalStateException if the Scanner stream is closed.
public String nextLine()
Returns the rest of the current input line. Note that the line terminator '\n' is read and
discarded; it is not included in the string returned.
Throws:
NoSuchElementException if there are no more lines.
IllegalStateException if the Scanner stream is closed.
public boolean hasNextLine()
Returns true if there is a next line. May wait for a next line to enter the stream.
Throws:
IllegalStateException if the Scanner stream is closed.
public Scanner useDelimiter(String newDelimiter);
Changes the delimiter for input so that newDelimiter will be the only delimiter that separates
words or numbers. See the subsection “Other Input Delimiters” in Chapter 2 for the details. (You
can use this method to set the delimiters to a more complex pattern than just a single string, but
we are not covering that.)
Returns the calling object, but we have always used it as a void method.
