Java Arrays fill(short[] a, int fromIndex, int toIndex, short val) Method

Description

The Java 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.)

Declaration

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

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

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

Filling the Array of shorts with Given Values Example

The following example shows the usage of Java Arrays fill(short[], short) method. First, we've created an array of shorts and its elements are printed. Using fill(short[], short) method, we're filling the array with a give value and then updated array elements are printed again.

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {
   public static void main(String[] args) {

      // initializing short array
      short arr[] = new short[] { 10 , 20, 15 };

      // let us print the values
      System.out.println("Actual values: ");
      for (short value : arr) {
         System.out.println("Value = " + value);
      }

      short replacement = 0;
      
      // using fill for placing value
      Arrays.fill(arr, replacement);

      // let us print the values
      System.out.println("New values after using fill() method: ");
      for (short value : arr) {
         System.out.println("Value = " + value);
      }
   }
}

Output

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

Actual values: 
Value = 10
Value = 20
Value = 15
New values after using fill() method: 
Value = 0
Value = 0
Value = 0

Filling the Sub-Array of shorts with Given Values Example

The following example shows the usage of Java Arrays fill(short[], int, int, short) method. First, we've created an array of shorts and its elements are printed. Using fill(short[], int, int, short) method method, we're filling the array with a give value and then updated array elements are printed again.

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {
   public static void main(String[] args) {

      // initializing short array
      short arr[] = new short[] { 10, 20, 15 };

      // let us print the values
      System.out.println("Actual values: ");
      for (short value : arr) {
         System.out.println("Value = " + value);
      }

      short replacement = 0;
      
      // using fill for placing value from index 0 to 3
      Arrays.fill(arr, 0, 3, replacement);

      // let us print the values
      System.out.println("New values after using fill() method: ");
      for (short value : arr) {
         System.out.println("Value = " + value);
      }
   }
}

Output

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

Actual values: 
Value = 10
Value = 20
Value = 15
New values after using fill() method: 
Value = 0
Value = 0
Value = 0

Filling the Sub-Array of shorts with Given Values Example

The following example shows the usage of Java Arrays fill(short[], int, int, short) method. First, we've created an array of shorts and its elements are printed. Using fill(short[], int, int, short) method method, we're filling the subarray of array with a give value and then updated array elements are printed again.

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {
   public static void main(String[] args) {

      // initializing short array
      short arr[] = new short[] { 10, 20, 15 };

      // let us print the values
      System.out.println("Actual values: ");
      for (short value : arr) {
         System.out.println("Value = " + value);
      }

      short replacement = 0;
      
      // using fill for placing value from index 0 to 2
      Arrays.fill(arr, 0, 2, replacement);

      // let us print the values
      System.out.println("New values after using fill() method: ");
      for (short value : arr) {
         System.out.println("Value = " + value);
      }
   }
}

Output

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

Actual values: 
Value = 10
Value = 20
Value = 15
New values after using fill() method: 
Value = 0
Value = 0
Value = 15
