1. Using for-each loop
2. Using Iterator inteface
3. Using ListIterator interface

for-each loop is like for loop which repeatedly executes a group of statements for each element of collection.The syntax of for-each loop is:

for(variable: collection-object)
{
Statements;
}

Note: Here, the variable assumes each element of the collection-object and the loop is executed as many times as there are number of elements in the collection-object.

Iterator is an interface that contains methods to retrieve the elements one by one from a collection object.It has three methods:

1. boolean hasnext(): This method returns true if the the iterator has more elements.
2. element next(): This method returns the next element in the iterator.
3. void remove(): This method removes from the collection the last element returned by the iterator.

ListIterator is an interface that contains methods to retrieve the elements from a collection object, both in forward and reverse direction.It has the following methods:

1. boolean hasnext(): This method returns true if the the ListIterator has more elements when traversing the list in the forward direction.
2. boolean hasPrevious(): This method returns true if the ListIterator has more elements when traversing the list in the reverse direction.
3. element next(): This method returns the next element in the list.
4. element previous(): This method returns the previous element in the list.
5. void remove(): This method removes from the list the last element that was returned by the next() or previous() methods.
