JAVA Data Structure ----- enumeration, java Data Structure -----

Although the Enumeration interface does not belong to a data structure, it is widely used in other data structures. The Enumeration interface defines a way to retrieve continuous elements from The data structure.

For example, enumeration defines a method called nextElement, which is used to obtain the next element of a Data Structure Containing Multiple elements.

Enumeration defines a hasMoreElements method, which is used to determine whether there are more elements.

Import java. util. vector; import java. util. enumeration; public class EnumerationTest {public static void main (String args []) {Enumeration months; Vector monthsNumber = new Vector (); monthsNumber. add ("January"); monthsNumber. add ("February"); monthsNumber. add ("March"); monthsNumber. add ("April"); monthsNumber. add ("May"); monthsNumber. add ("June"); monthsNumber. add ("July"); monthsNumber. add ("August"); monthsNumber. add ("September"); monthsNumber. add ("October"); monthsNumber. add ("November"); monthsNumber. add ("December"); months = monthsNumber. elements (); while (months. hasMoreElements () {System. out. println (months. nextElement ());}}}
