createReverseIteratorback to summary
public static <T> Iterator<T> createReverseIterator(List<T> list)

Returns an Iterator iterating the given list from the end to the start.

I.e. the iterator does the reverse of the List#iterator().

Parameters
<T>
Type of elements in the list
list:List<T>

 

Returns:Iterator<T>

a reverse Iterator of the list

public boolean hasNext()

Implements java.util.Iterator.hasNext.

Doc from java.util.Iterator.hasNext.

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Returns:boolean

true if the iteration has more elements

Returns the next element in the iteration.

Returns:T

removeback to summary
public void remove()

Overrides default java.util.Iterator.remove.

Doc from java.util.Iterator.remove.

Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next.

The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy.

The behavior of an iterator is unspecified if this method is called after a call to the forEachRemaining method.
