public boolean containsAll(Collection <?> c)

Example

In the following code shows how to use Vector.containsAll(Collection <?> c) method.

/*from  w  ww .  j  a  v  a2s.  c om*/
import java.util.Vector;

public class Main {
   public static void main(String[] args) {
      Vector<Integer>  vec = new Vector<Integer> (4);
      Vector<Integer>  vectest = new Vector<Integer> (4);
      Vector<Integer>  vecdiff = new Vector<Integer> (4);

      vec.add(4);
      vec.add(3);
      vec.add(2);   
      
      vectest.add(4);
      vectest.add(3);
      vectest.add(2);
      
      vecdiff.add(4);
      vecdiff.add(3);
      vecdiff.add(12);

      // let us check vec and vectest
      System.out.println(vectest.containsAll(vec));   
      
      // let us check vec and vecdiff
      System.out.println(vecdiff.containsAll(vec)); 
   }
}

The code above generates the following result.
