I need to count the occurence of each string given in the vector from the text file.I have the file and the vector.How do i compare the vector and textfile ,so that i can count the occurence of eachString in the vector with the text file.The text file may contain any of the words given in the vector.If found ,a count shld be made for each string .

Try this code:
import java.util.*;
import java.io.*;
class Count
public static void main(String args[ ] )throws Exception
     FileReader     fr = new FileReader("c.c");
     BufferedReader br = new BufferedReader(fr);
     StringBuffer   sb = new StringBuffer();
     String         s;
     while((s=br.readLine())!=null)
          sb.append(s);
     s=sb.toString();
     Vector v= new Vector();
     v.addElement("job");
     v.addElement("jobs");
     v.addElement("career");
     v.addElement("careers");
     v.addElement("vacancy");
     v.addElement("vacancies");
     v.addElement("opportunity");
     v.addElement("openings");
     v.addElement("posting");
     v.addElement("postings");
     v.addElement("opportunities");
     v.addElement("placement");
     v.addElement("placements");
     Enumeration vEnum=v.elements();
     while(vEnum.hasMoreElements())
          String l = (String)vEnum.nextElement();
          int    a = 0;
          int    p = s.indexOf(l,a);
          int    c = 0;
          while (p != -1)
               c = c + 1;
               a = a + l.length() + p;
               p = s.indexOf(l,a);
          System.out.println(l+"  "+c);
}
