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:
Program 1:
// Java code to demonstrate getShort() method of Array classimport java.lang.reflect.Array;public class GfG { // 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 + " "); } }} |
Output:
1 2 3 4 5
Program 2: To demonstrate java.lang.ArrayIndexOutOfBoundsException.
// Java code to demonstrate getShort() method in Arrayimport java.lang.reflect.Array; public class GfG { // main method public static void main(String[] args) { // Declaring and defining a short array short a[] = {1, 2, 3, 4, 5}; try { // invalid index short x = Array.getShort(a, 6); System.out.println(x); } catch (Exception e) { // throws Exception System.out.println("Exception : " + e); } }} |
Output:
Exception : java.lang.ArrayIndexOutOfBoundsException
Program 3: To demonstrate java.lang.NullPointerException.
// Java code to demonstrate getShort() method in Arrayimport java.lang.reflect.Array; public class GfG { // main method public static void main(String[] args) { // Declaring and defining a short array to null short a[] = null; try { // null Object Array short x = Array.getShort(a, 6); System.out.println(x); } catch (Exception e) { // throws Exception System.out.println("Exception : " + e); } }} |
Output:
Exception : java.lang.NullPointerException
Program 4: To demonstrate java.lang.IllegalArgumentException.
// Java code to demonstrate getShort() method in Arrayimport java.lang.reflect.Array; public class GfG { // main method public static void main(String[] args) { // Declaring and defining a short variable short a = 10; try { // illegalArgument short x = Array.getShort(a, 6); System.out.println(x); } catch (Exception e) { // throws Exception System.out.println("Exception : " + e); } }} |
Output:
Exception : java.lang.IllegalArgumentException: Argument is not an array
