The toArray() method of Shorts Class in the Guava library is used to convert the short values, passed as the parameter to this method, into a Short Array. These short values are passed as a Collection to this method. This method returns a Short array.
Syntax:
public static short[] toArray(Collection<? extends Number> collection)
Parameters: This method accepts a mandatory parameter collection which is the collection of short values to be converted in to a Short array.
Return Value: This method returns a short array containing the same values as a collection, in the same order.
Exceptions: This method throws NullPointerException if the passed collection or any of its elements is null.
Below programs illustrate the use of toArray() method:
Example 1:
// Java code to show implementation of// Guava's Shorts.toArray() method  import com.google.common.primitives.Shorts;import java.util.Arrays;import java.util.List;  class GFG {      // Driver's code    public static void main(String[] args)    {          // Creating a List of Shorts        List<Short> myList            = Arrays.asList((short)1, (short)2,                            (short)3, (short)4, (short)5);          // Using Shorts.toArray() method to convert        // a List or Set of Short to an array of Short        short[] arr = Shorts.toArray(myList);          // Displaying an array containing each        // value of collection,        // converted to a short value        System.out.println(Arrays.toString(arr));    }} |
