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.
- 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.
// 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:
