Examples of java.util.Vector.clear()

java.util.Vector.clear()
Removes all of the elements from this Vector. The Vector will be empty after this call returns (unless it throws an exception). @since 1.2

        Vector v = new Vector(); 
        Vector testv = new MockVector();
        // though size is overriden, it should passed without exception
        testv.add(1);
        testv.add(2);
        testv.clear();
        
        testv.add(1);
        testv.add(2);
        v.add(1);
        v.add(2);
