ShortBuffer allocate() method in Java

A new ShortBuffer can be allocated using the method allocate() in the class java.nio.ShortBuffer. This method requires a single parameter i.e. the capacity of the buffer. It returns the new ShortBuffer that is allocated. If the capacity provided is negative, then the IllegalArgumentException is thrown.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.nio.*; import java.util.*; public class Demo {    public static void main(String[] args) {       int n = 5;       try {          ShortBuffer buffer = ShortBuffer.allocate(5);          buffer.put((short)12);          buffer.put((short)91);          buffer.put((short)25);          buffer.put((short)18);          buffer.put((short)30);          buffer.rewind();          System.out.println("The ShortBuffer is: " + Arrays.toString(buffer.array()));       } catch (IllegalArgumentException e) {          System.out.println("Error!!! IllegalArgumentException");       } catch (ReadOnlyBufferException e) {          System.out.println("Error!!! ReadOnlyBufferException");       }    } }

The output of the above program is as follows −

Output

The ShortBuffer is: [12, 91, 25, 18, 30]
