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 + " " );
}
}
} |
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);
}
}
} |
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);
}
}
} |
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);
}
}
} |
Exception : java.lang.IllegalArgumentException: Argument is not an array
