Questions tagged [nosuchelementexception]

Use this tag if your problem is caused by or primarily involves a NoSuchElementException in Java.

The NoSuchElementException is a RuntimeException thrown by the nextElement method of an Enumeration to indicate that there are no more elements in the enumeration.

It is also thrown by:

  • the various next* methods (nextInt, nextFloat, nextLine,...) of the Scanner class when input is exhausted;
  • the get method of the Java 8 Optional class when a value is not present;
  • the methods firstElement and lastElement in the Vector class when there are no elements;
  • the methods firstKey and lastKey in the TreeMap class when there are no keys;
  • the methods getFirst, getLast, removeFirst and removeLast in LinkedList when there are no elements;

and other collections.
