Java Arrays - spliterator() Method

The java.util.Arrays.spliterator() method returns a Spliterator covering the specified range of the specified array.

Syntax

static <T> Spliterator<T> spliterator(T[] array,
                                      int startInclusive,
                                      int endExclusive)

Here, T is the type of elements in the array.

Parameters

`array`	Specify the array, assumed to be unmodified during use.
`startInclusive`	Specify the first index to cover, inclusive.
`endExclusive`	Specify the index immediately past the last index to cover.

Return Value

Returns a spliterator for the array elements.

Exception

Throws ArrayIndexOutOfBoundsException, if startInclusive is negative, endExclusive is less than startInclusive, or endExclusive is greater than the array size.

Example:

In the example below, the java.util.Arrays.spliterator() method returns a spliterator with elements in specified range of the given array object.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a Long array
    Long[] MyArr = {10l, 2l, -3l, 35l, 56l};

    //creating spliterator object on Array 
    Spliterator<Long> splitr = Arrays.spliterator(MyArr, 1, 4); 

    //printing estimateSize of the Array
    System.out.println("Estimated size: " + splitr.estimateSize());  

    //display content of the Array using 
    //tryAdvance method
    System.out.print("The Array contains: ");              
    splitr.forEachRemaining((n) -> System.out.print(n + " "));    
  }
}

The output of the above code will be:

Estimated size: 3
The Array contains: 2 -3 35
