Stack removeRange() method in Java with Example
The removeRange() method of Stack in Java is used to remove all elements within the specified range from an Stack object. It shifts any succeeding elements to the left. This call shortens the stack by (toIndex-fromIndex) elements where toIndex is the ending index and fromIndex is the starting index within which all elements are to be removed. (If toIndex==fromIndex, this operation has no effect)
removeRange(int fromIndex, int toIndex)
Parameters: This method takes two parameters:
- fromIndex: starting index from which index elements are to be removed.
- toIndex: within range[fromIndex-toIndex), all elements are removed.
Return Value: This method does not return any value. It only removes all the elements within the specified range.
Exceptions: This method throws indexOutOfBoundsException if fromIndex or toIndex is out of range (fromIndex = size() or toIndex > size() or toIndex < fromIndex)
Below examples illustrate the Stack.removeRange() method:
