Array getShort() method in Java

The java.lang.reflect.Array.getShort() is an in-built method of Array class in Java and is used to return the element present at a given index from the specified Array as a short.

Syntax:

Array.getShort(Object []array,int index)

Parameters:



  • array: The object array whose index is to be returned.
  • index: The particular index of the given array. The element at ‘index’ in the given array is returned.

Return Type: This method returns the element of the array as short.

Note: Typecast isn’t necessary as the return type is short.

Exceptions: This method throws following exceptions:

  • NullPointerException – when the array is null.
  • IllegalArgumentException – when the given object array is not an Array.
  • ArrayIndexOutOfBoundsException – if the given index is not in the range of the size of the array.

Below programs illustrate the getShort() method of Array class:

// Java code to demonstrate getShort() method of Array class

    // main method
    public static void main(String[] args) {
           
       // Declaring and defining a short array
       short a[] = {1,2,3,4,5};
          
       // Traversing the array
       for(int i = 0;i<5;i++){
              
           // Array.getShort() method
              
           short x = Array.getShort(a, i);
           // Printing the values
           System.out.print(x + " ");
       }
           
    }
