RETokenizer

public class RETokenizer implements Enumeration(Code)

The Tokenizer class suggests a methods to break a text into tokens using occurences of a pattern as delimiters. There are two ways to obtain a text tokenizer for some pattern:

 Pattern p=new Pattern("\\s+"); //any number of space characters
 String text="blah blah blah";
 //by factory method
 RETokenizer tok1=p.tokenizer(text);
 //or by constructor
 RETokenizer tok2=new RETokenizer(p,text);

Now the one way is to use the tokenizer as a token enumeration/iterator:

 while(tok1.hasMore()) System.out.println(tok1.nextToken());

and another way is to split it into a String array:

 
 String[] arr=tok2.split();
 for(int i=0;i
