Vector v = new Vector();
        v.add(1);
        v.add(2);
        v.add(1);

        int OnesCount = 0;
        for (int x = 0; x < v.size(); x++){
           int i = (Integer)v.elementAt(x);
           if (i == 1){
               OnesCount++;
           }
        }
        System.out.println(OnesCount);

Thanks for your code..
but in my code

Vector v = new Vector();
Vector v1 = new Vector();
 
v contains some string .
v1 also contains some string.

v.size() will give you the number of elements.

If you have strings in your vectors you can do this...


Vector v = new Vector();
        v.add("1");
        v.add("2");
        v.add("1");

        int OnesCount = 0;
        for (int x = 0; x < v.size(); x++){
           String i = (String)v.elementAt(x);
           if (i.equals("1")){
               OnesCount++;
           }
        }
        System.out.println(OnesCount);
