Methods and APIs Description

StringTokenizer(String str)

This constructor is used to creates token of the given string. It is takeing a string type value as a parameter and tokenized it. The passed string is the collection of multiple sets like: Tab character ("\t"), blank space (" "), new line character ("\n") etc.


This method is used to check the token created by the StringTokenizer() methods. It returns Boolean type value either true or false. If the above method returns true then the nextToken() method is called.


This method returns the tokenized string which is the separate word of the given string. Through the help of the available spaces this method distinguish between words.


package r4r;
import java.util.*;
public class breakstringtest {
	String str;
	  int count = 0;
public static void main(String[] args)
breakstringtest c = new breakstringtest(); } public breakstringtest(){ try{ InputStreamReader isr = new InputStreamReader(; BufferedReader br = new BufferedReader(isr); System.out.print("Enter the String: "); str = br.readLine(); System.out.println("Enter String is : "+ str); System.out.println("Break this string : "); StringTokenizer tok = new StringTokenizer(str); while (tok.hasMoreTokens()){ count++; str = tok.nextToken(); System.out.println(str); } System.out.println("Number of Words is : "+ count); } catch(IOException e){} } }


Enter the String: Ram is a god
