Exception

NA

Java Arrays spliterator​(int[] a, int fromIndex, int toIndex) Method

Description

The Java Arrays spliterator(int[] a, int fromIndex, int toIndex) method returns a Spliterator.OfInt covering the specified range of the specified array.

Declaration

Following is the declaration for java.util.Arrays.spliterator(int[] a, int fromIndex, int toIndex) method

public static Spliterator.OfInt spliterator​(int[] array, int fromIndex, int toIndex)

Parameters

• a − This is the array, assumed to be unmodified during use.

• fromIndex − This is the index of the first element, inclusive, to be covered.

• toIndex − This is the index of the last element, exclusive, to be covered

Return Value

This method returns a spliterator for the array elements.

Exception

• ArrayIndexOutOfBoundsException − if fromIndex < 0 or toIndex > array.length

Getting Spliterator of Array of ints Example

The following example shows the usage of Java Arrays spliterator(int[]) method. First, we've created an array of ints. Using spliterator() method, array is printed thereafter.

package com.tutorialspoint;

import java.util.Arrays;
import java.util.Spliterator;

public class ArrayDemo {
   public static void main(String[] args) {
      // initialize array
      int arr[] = { 11, 54, 23, 32, 15, 24, 31, 12 };

      System.out.print("Array: [ ");
      
      // get the spliterator
      Spliterator<Integer> spliterator = Arrays.spliterator(arr);

      // use the spliterator to print each item
      spliterator.forEachRemaining(i -> System.out.print(i + " "));
      
      System.out.print("]");
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Array: [ 11 54 23 32 15 24 31 12 ]

Getting Spliterator of Array of ints using Range Example

The following example shows the usage of Java Arrays spliterator(int[], int, int) method. First, we've created an array of ints. Using spliterator() method, array is printed thereafter.

package com.tutorialspoint;

import java.util.Arrays;
import java.util.Spliterator;

public class ArrayDemo {
   public static void main(String[] args) {
      // initialize array
      int arr[] = { 11, 54, 23, 32, 15, 24, 31, 12 };

      System.out.print("Array: [ ");
      
      // get the spliterator
      Spliterator<Integer> spliterator = Arrays.spliterator(arr, 0, arr.length);

      // use the spliterator to print each item
      spliterator.forEachRemaining(i -> System.out.print(i + " "));
      
      System.out.print("]");
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Array: [ 11 54 23 32 15 24 31 12 ]

Getting Spliterator of Sub-Array of ints Example

The following example shows the usage of Java Arrays spliterator(int[], int, int) method. First, we've created an array of ints. Using spliterator() method, a sub-array is printed thereafter.

package com.tutorialspoint;

import java.util.Arrays;
import java.util.Spliterator;

public class ArrayDemo {
   public static void main(String[] args) {
      // initialize array
      int arr[] = { 11, 54, 23, 32, 15, 24, 31, 12 };

      System.out.print("Array: [ ");
      
      // get the spliterator
      Spliterator<Integer> spliterator = Arrays.spliterator(arr, 0, 5);

      // use the spliterator to print each item
      spliterator.forEachRemaining(i -> System.out.print(i + " "));
      
      System.out.print("]");
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Array: [ 11 54 23 32 15 ]
