Fill a Short Array using Index in Java

Declaration :

public static void fill(short[] a, int fromIndex, int toIndex, short val)

1	public static void fill(short[] a, int fromIndex, int toIndex, short val)

Explanation :

Purpose	The java.util.Arrays.fill(short[] a int fromIndex int toIndex short val) method assigns the specified short value to each element of the specified range of the specified array of shorts. The range to be filled extends from index fromIndex inclusive to index toIndex exclusive.(If fromIndex==toIndex the range to be filled is empty.).
Parameters	a ===> This is the array to be filled.
	fromIndex ===> This is the index of the first element (inclusive) to be filled with the specified value.
	toIndex ===> This is the index of the last element (exclusive) to be filled with the specified value.
	val ===> This is the value to be stored in all elements of the array.
Return Value	This method does not return any value.
Exception	ArrayIndexOutOfBoundsException — if fromIndex < 0 or toIndex > a.length ,IllegalArgumentException — if fromIndex > toIndex

Java Program : Example

Below example will explain java.util.Arrays.fill() method.

package com.c4learn;
import java.util.Arrays;
public class ArrayDemo {
	public static void main(String[] args) {
		// Initialize a short array
		short arr[] = new short[] { 5, 10, 15, 20, 25 };
		// Print the original array
		System.out.println("Original Array : ");
		for (short val : arr) {
			System.out.println("Original element is " + val);
		}
		// Use fill to place 35 in the range index 0 to 3
		Arrays.fill(arr, 0, 3, (short) 35);
		// Print the new array
		System.out.println("\nNew Array is : ");
		for (short val : arr) {
			System.out.println("New element is " + val);
		}
	}
}

package com.c4learn;

import java.util.Arrays;

public class ArrayDemo {

public static void main(String[] args) {

// Initialize a short array

short arr[] = new short[] { 5, 10, 15, 20, 25 };

// Print the original array

System.out.println("Original Array : ");

for (short val : arr) {

System.out.println("Original element is " + val);

}

// Use fill to place 35 in the range index 0 to 3

Arrays.fill(arr, 0, 3, (short) 35);

// Print the new array

System.out.println("\nNew Array is : ");

for (short val : arr) {

System.out.println("New element is " + val);

}

Output of Program :

Original Array : 
Original element is 5
Original element is 10
Original element is 15
Original element is 20
Original element is 25
New Array is : 
New element is 35
New element is 35
New element is 35
New element is 20
New element is 25

Original Array :

Original element is 5

Original element is 10

Original element is 15

Original element is 20

Original element is 25

New Array is :

New element is 35

New element is 20

New element is 25
