Java Iterator Interface
Java Iterator Methods
The Iterator
interface provides methods to access and iterate through collections:
Method | Description | Return Type |
---|---|---|
hasNext() | Returns true if there are more elements in the iteration | boolean |
next() | Returns the next element in the iteration | T |
remove() | Removes the last element returned by next() | void |
Note: The next()
method uses the type of the iterator's items as its return value. This type is referred to as T in the table.
