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