hasMoreElements

HasMoreElements is a method of the java.util.Enumeration interface in the Java standard library. It returns a boolean indicating whether there are more elements to be retrieved from the enumeration by calling nextElement(). The method signature is boolean hasMoreElements().

Enumeration provides a forward-only, read-only way to iterate over a set of elements. It does not support removal of elements. If hasMoreElements() returns true, nextElement() will return the next element; if it returns false, calling nextElement() would typically throw NoSuchElementException.

Typical usage involves obtaining an Enumeration from a legacy API and iterating until there are no more elements. For example, Enumeration<String> e = someCollection.elements(); while (e.hasMoreElements()) { String s = e.nextElement(); … }

Relation to modern iteration: hasMoreElements() is part of the older Enumeration API, which predates the Java Collections Framework. The more common modern interface is Iterator, which uses hasNext(), next(), and an optional remove() method. For new code, Iterator or the enhanced for loop is generally preferred over Enumeration.

Legacy status and conversions: Enumeration remains for backward compatibility with APIs such as Vector, Hashtable, and Properties. If needed, an Enumeration can be converted to a List using Collections.list(e) to work with newer collection utilities.
