Class java.util.StringTokenizer 

java.lang.Object
|
   +----java.util.StringTokenizer
public class StringTokenizer
extends Object
implements Enumeration
StringTokenizer is a class that controls simple linear tokenization of a String. The set of delimiters, which defaults to common whitespace characters, may be specified at creation time or on a per-token basis.

Example usage: 

String s = "this is a test";
	StringTokenizer st = new StringTokenizer(s);
	while (st.hasMoreTokens()) {
		println(st.nextToken());
	}
Prints the following on the console: 
this
	is
	a
	test

Constructor Index

o StringTokenizer(String)
Constructs a StringTokenizer on the specified String, using the default delimiter set (which is " \t\n\r").
o StringTokenizer(String, String)
Constructs a StringTokenizer on the specified String, using the specified delimiter set.
o StringTokenizer(String, String, boolean)
Constructs a StringTokenizer on the specified String, using the specified delimiter set.

Method Index

o countTokens()
Returns the next number of tokens in the String using the current deliminter set.
o hasMoreElements()
Returns true if the Enumeration has more elements.
o hasMoreTokens()
Returns true if more tokens exist.
o nextElement()
Returns the next element in the Enumeration.
o nextToken()
Returns the next token of the String.
o nextToken(String)
Returns the next token, after switching to the new delimiter set.

Constructors

o StringTokenizer 
public StringTokenizer(String str,
String delim,
                         boolean returnTokens)
Constructs a StringTokenizer on the specified String, using the specified delimiter set.
Parameters:
str - the input String
delim - the delimiter String
returnTokens - returns delimiters as tokens or skip them
o StringTokenizer 
public StringTokenizer(String str,
String delim)
Constructs a StringTokenizer on the specified String, using the specified delimiter set.
Parameters:
str - the input String
delim - the delimiter String
o StringTokenizer 
public StringTokenizer(String str)
Constructs a StringTokenizer on the specified String, using the default delimiter set (which is " \t\n\r").
Parameters:
str - the String

Methods

o hasMoreTokens 
public boolean hasMoreTokens()
Returns true if more tokens exist.
o nextToken 
public String nextToken()
Returns the next token of the String.
Throws: NoSuchElementException
If there are no more tokens in the String.
o nextToken 
public String nextToken(String delim)
Returns the next token, after switching to the new delimiter set. The new delimiter set remains the default after this call.
Parameters:
delim - the new delimiters
o hasMoreElements 
public boolean hasMoreElements()
Returns true if the Enumeration has more elements.
o nextElement 
public Object nextElement()
Returns the next element in the Enumeration.
Throws: NoSuchElementException
If there are no more elements in the enumeration.
o countTokens 
public int countTokens()
Returns the next number of tokens in the String using the current deliminter set. This is the number of times nextToken() can return before it will generate an exception. Use of this routine to count the number of tokens is faster than repeatedly calling nextToken() because the substrings are not constructed and returned for each token.
