The java.lang.reflect.Array.setShort() is an inbuilt method in Java and is used to set a specified short value to a specified index of a given object array. Syntax: 
Array.setShort(Object []array,int index, short value)
Parameters: This method takes 3 parameters:
  • array: This is an array of type Object which is to be updated.
  • index: This is the index of the array which is to be updated.
  • value: This is the short value that is to be set at the given index of the given array.
Exception: 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 is the implementation of Array.setShort() method: Program 1 : Java 
    // Java code to demonstrate 
// setShort() method of Array class

import java.lang.reflect.Array;
public class GfG {
    // main method
    public static void main(String[] args) {
        
        // Declaring and defining Short array
        short b[] = {1,2,3,4};
        System.out.print("Before Set : ");
        // printing the array
        for(short x : b){
            System.out.print(x + " ");
        }
        short value = 10;
        // set method of class Array
        Array.setShort(b, 1, value);
        
        System.out.print("\nAfter Set : ");
        // printing array
        for(short x : b){
            System.out.print(x + " ");
        }
        
    }
}
    Output: 
    Before Set : 1 2 3 4 
After Set : 1 10 3 4
    Program 2 : to demonstrate java.lang.NullPointerException Java 
    // Java code to demonstrate 
// setShort() method of Array class

import java.lang.reflect.Array;
public class GfG {
    // main method
    public static void main(String[] args) {
        
        // Declaring and defining Short array to null
        short b[] = null;
        try{
            short s = 10;
            Array.setShort(b,5,s);
        }
        catch(Exception e){
            System.out.println("Exception : " + e);
        }
        
    }
}
    Output: 
    Exception : java.lang.NullPointerException
    Program 3: To demonstrate java.lang.ArrayIndexOutOfBoundsException Java 
    // Java code to demonstrate 
// setShort() method of Array class

import java.lang.reflect.Array;
public class GfG {
    // main method
    public static void main(String[] args) {
        
        // Declaring and defining Short array
        short b[] = {1,2,3,4};
        try{
            short s = 10;
            Array.setShort(b,5,s);
        }
        catch(Exception e){
            System.out.println("Exception : " + e);
        }
        
    }
}
    Output: 
    Exception : java.lang.ArrayIndexOutOfBoundsException
    Program 4: To demonstrate java.lang.IllegalArgumentException Java 
    // Java code to demonstrate 
// setShort() method of Array class
import java.lang.reflect.Array;
public class GfG {
    // main method
    public static void main(String[] args) {
        
        // Declaring and defining Short variable
        short b = 1;
        try{
            short s = 10;
            Array.setShort(b,5,s);
        }
        catch(Exception e){
            System.out.println("Exception : " + e);
        }
        
    }
}
    Output: 
    Exception : java.lang.IllegalArgumentException: Argument is not an array
