Array setShort() method in Java

Array.setShort(Object []array,int index, short value)

• 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.

• 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
