Examples of java.util.Vector.elementAt()

java.util.Vector.elementAt()
Returns the component at the specified index.
This method is identical in functionality to the {@link #get(int)}method (which is part of the {@link List} interface). @param index an index into this vector @return the component at the specified index @throws ArrayIndexOutOfBoundsException if the index is out of range( {@code index < 0 || index>= size()})
