Get Enumeration over Java ArrayList Example
This java example shows how to get Enumeration over Java ArrayList using
enumeration method of Collections class. This example also shows how to enumerate
through elements of Java ArrayList.

Get Enumeration over Java ArrayList object using,
static Enumeration enumeration(Collection c) method of Collections class.
This method returns the enumeration object over the specified Collection.

//get the Enumeration object
Enumeration e = Collections.enumeration(arrayList);
//enumerate through the ArrayList elements
System.out.println("Enumerating through Java ArrayList");
while(e.hasMoreElements())

/*
Output would be
Enumerating through Java ArrayList
A
B
D
E
F
