String Tokenizer

String Tokenizer:-

Using StringTokenizer you can easily Split String into Tokens.

We can use StringTokenizer using following method;-

StringTokenizer(String str)
StringTokenizer(String str, String delimiters)  

 

Here is simple Example.

 StringTokenizer strTo = new StringTokenizer("x-y-z", "-");
 while (st.hasMoreTokens()) 

 {
     System.out.println(st.nextToken());
 }

Another way:-
 for (String token : "x-y-z".split("-")) 

 {
     System.out.println(token);
 }

Simple java Example:-

public class Test {
public static void main(String[] args) {
    String str="this is=android{welcome}";
    StringTokenizer st = new StringTokenizer(str,"={}");

    System.out.println("---- Split by sp");
    while (st.hasMoreElements()) {
        String profile=st.nextElement().toString();
        String name=st.nextElement().toString();
        System.out.println("profile="+ profile +"name="+ name);
    }

    System.out.println("---- Split by comma ',' ------");
    StringTokenizer st2 = new StringTokenizer(str, ",");

    while (st2.hasMoreElements())
    {
        System.out.println(st2.nextElement());
    }
   
}
}

o/p:-

---- Split by sp
profile=this,is

name=android

other=welcome

---- Split by comma ',' ------
this
is=android{welcome}

Explanation:-

1> public int countTokens ()

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().

2>public boolean hasMoreElements ()

Returns

• true if unprocessed tokens remain.

3>public boolean hasMoreTokens ()

Returns

• true if unprocessed tokens remain.

4>public Object nextElement ()

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.

5>public String nextToken (string delims)

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.
