ShortBuffer allocate() method in Java

Java 8Object Oriented ProgrammingProgramming

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]
