public class

StringTokenizer

extends Object
implements Enumeration<E>

java.lang.Object
↳	java.util.StringTokenizer

Class Overview

Breaks a string into tokens; new code should probably use split(String).

 // Legacy code:
 StringTokenizer st = new StringTokenizer("a:b:c", ":");
 while (st.hasMoreTokens()) {
     System.err.println(st.nextToken());
 }

 // New code:
 for (String token : "a:b:c".split(":")) {
     System.err.println(token);
 }

Summary

Public Constructors
	StringTokenizer(String string) Constructs a new `StringTokenizer` for the parameter string using whitespace as the delimiter.
	StringTokenizer(String string, String delimiters) Constructs a new `StringTokenizer` for the parameter string using the specified delimiters.
	StringTokenizer(String string, String delimiters, boolean returnDelimiters) Constructs a new `StringTokenizer` for the parameter string using the specified delimiters, returning the delimiters as tokens if the parameter `returnDelimiters` is `true`.

Public Methods
int	countTokens() Returns the number of unprocessed tokens remaining in the string.
boolean	hasMoreElements() Returns `true` if unprocessed tokens remain.
boolean	hasMoreTokens() Returns `true` if unprocessed tokens remain.
Object	nextElement() Returns the next token in the string as an `Object`.
String	nextToken(String delims) Returns the next token in the string as a `String`.
String	nextToken() Returns the next token in the string as a `String`.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

From interface java.util.Enumeration

Public Constructors

public StringTokenizer (String string)

Since: API Level 1

Constructs a new StringTokenizer for the parameter string using whitespace as the delimiter. The returnDelimiters flag is set to false.

Parameters

string	the string to be tokenized.

public StringTokenizer (String string, String delimiters)

Since: API Level 1

Constructs a new StringTokenizer for the parameter string using the specified delimiters. The returnDelimiters flag is set to false. If delimiters is null, this constructor doesn't throw an Exception, but later calls to some methods might throw a NullPointerException.

Parameters

string	the string to be tokenized.
delimiters	the delimiters to use.

public StringTokenizer (String string, String delimiters, boolean returnDelimiters)

Since: API Level 1

Constructs a new StringTokenizer for the parameter string using the specified delimiters, returning the delimiters as tokens if the parameter returnDelimiters is true. If delimiters is null this constructor doesn't throw an Exception, but later calls to some methods might throw a NullPointerException.

Parameters

string	the string to be tokenized.
delimiters	the delimiters to use.
returnDelimiters	`true` to return each delimiter as a token.

Public Methods

public int countTokens ()

Since: API Level 1

Returns the number of unprocessed tokens remaining in the string.

Returns

number of tokens that can be retreived before an Exception will result from a call to nextToken().

public boolean hasMoreElements ()

Since: API Level 1

Returns true if unprocessed tokens remain. This method is implemented in order to satisfy the Enumeration interface.

Returns

true if unprocessed tokens remain.

public boolean hasMoreTokens ()

Since: API Level 1

Returns true if unprocessed tokens remain.

Returns

true if unprocessed tokens remain.

public Object nextElement ()

Since: API Level 1

Returns the next token in the string as an Object. This method is implemented in order to satisfy the Enumeration interface.

Returns

next token in the string as an Object

Throws

NoSuchElementException	if no tokens remain.

public String nextToken (String delims)

Since: API Level 1

Returns the next token in the string as a String. The delimiters used are changed to the specified delimiters.

Parameters

delims	the new delimiters to use.

Returns

next token in the string as a String.

Throws

NoSuchElementException	if no tokens remain.

public String nextToken ()

Since: API Level 1

Returns the next token in the string as a String.

Returns

next token in the string as a String.

Throws

NoSuchElementException	if no tokens remain.
