Hello Suma,

Here is the code:


import java.lang.*;
import java.util.*;
public class NoOfOccurence
{
public static void main(String args[])
{
String str = "welcome to java world. In java world";
StringTokenizer st = new StringTokenizer(str,"[ .]");
Vector vec= new Vector(10);
HashSet s = new HashSet();
while (st.hasMoreTokens())
{
vec.addElement(st.nextToken());
}
for (int i = 0; i {
int count = 0;
for (int j = 0; j {
if(vec.elementAt(i).equals(vec.elementAt(j)))
{
count = count + 1;
}
}
if (s.add(vec.elementAt(i)))
System.out.println(vec.elementAt(i) +"="+ count);
}
}
}

Regards,
