Theses are all true and false questions:

The interface ListIterator provides methods such as next and previous to iterate over the elements of a LinkedList object.

The FlowLayout places components in the container from left to right.

GUI components are placed in a window called JFrame.

Item events are handled by the listener ItemListener, which contains the abstract method actionPerformed.

The layout manager FlowLayout places components in the container from left to right until no more items can be placed.

A Vector object is a collection.

To place more than one component in an area on a container, you add each component directly to the area.

One way to iterate over the elements of a collection is to use iterators.

Most of the Java Collections Framework classes and interfaces are in the java.collect package.

The method public void addLast(E obj) of the class LinkedList appends the element specified by the parameter obj to the end of the list.

It is impossible to convert a GUI application into an applet.

The BorderLayout places components in one of four areas around the border of a container.

A LinkedList can hold any type of variable or object.

Sometimes it is necessary to process all the elements of a collection one by one.

The method hasNext() of the interface ListIterator returns true if the list iterator has more elements when traversing the list in the reverse direction.

The class LinkedList is derived from the abstract class AbstractSet.

A JCombobox allows the user to select more than one item from a list.

GridLayout places components in a table format with rows and columns.

The interface Collection is the super class (interface) of all Java collection classes.

Objects in a LinkedList are connected by a reference.

Java provides a number of interfaces and classes to systematically implement collections.

The method public int size() of the class LinkedList returns the number of elements in the list.

Typically, an iterator moves in both directions, starting at either the first or the last element of the collection.

To be able to handle a variety of events, Java allows a class to implement more than one interface.

Every element in a LinkedList object points to both its immediate predecessor and its immediate successor (including the first and last elements).
