Better code for hashtables

Question

Hi all.
I have a vector which contains a lot of string. Then i have another string which is called keyword. So, for example:
Vector v = new Vector();
v.add("Sam went to the hospital today");
v.add("They told him he had the flu");
v.add("The hospital had arranged now arranged a second meetin")
v.add(" Sam will come back then");
String Key =  " hospital;What i need to do is find in which vector position does hospital occur and give it a score. So i also need a way of storing the sentence again and assigning it a value i.e. (Sam went to the hospital today, 20). The value is preset. Any help would be much appreciated. Many thanks.

hi,
here i am giving example on hash table.
please follow.
import java.util.*;
public class SortHashtable {
public static void main(String[] args) {
// Create and populate hashtable
Hashtable ht = new Hashtable();
ht.put("abc",new Double(3445.23));
ht.put("xyz",new Double(2333.56));
ht.put("pqr",new Double(3900.88));
ht.put("mno",new Double(2449.00));
// Sort hashtable.
Vector v = new Vector(ht.keySet());
Collections.sort(v);
// Display (sorted) hashtable.
for (Enumeration e = v.elements(); e.hasMoreElements();) {
String key = (String)e.nextElement();
System.out.println(key+":"+ht.get(key));
System.out.println();
i hope u get what u want
