# 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");
}
The ShortBuffer is: [12, 91, 25, 18, 30]
