Array getShort() method in Java

Last Updated : 30 Nov, 2018

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 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 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 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 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
