Método ShortBuffer slice() en Java con ejemplos

El método slice() de java.nio.ShortBuffer Class se utiliza para crear un nuevo búfer corto cuyo contenido es una subsecuencia compartida del contenido de este búfer. 

El contenido del nuevo búfer comenzará en la posición actual de este búfer. Los cambios en el contenido de este búfer serán visibles en el nuevo búfer y viceversa; los valores de posición, límite y marca de los dos búferes serán independientes. 
La posición del nuevo búfer será cero, su capacidad y su límite será el número de cortos que queden en este búfer, y su marca será indefinida. El nuevo búfer será directo si, y solo si, este búfer es directo, y será de solo lectura si, y solo si, este búfer es de solo lectura.

Sintaxis : 

public abstract ShortBuffer slice()

Valor devuelto : este método devuelve el nuevo búfer corto.

A continuación se muestran los ejemplos para ilustrar el método slice() :

Programa 1 : 

// Java program to demonstrate
// slice() method
 
import java.nio.*;
import java.util.*;
 
public class GFG {
 
    public static void main(String[] args)
    {
 
        // Declaring the capacity of the ShortBuffer
        int capacity = 10;
 
        // Creating the ShortBuffer
        try {
 
            // creating object of Shortbuffer
            // and allocating size capacity
            ShortBuffer sb1 = ShortBuffer.allocate(capacity);
 
            // putting the value in Shortbuffer
            sb1.put((short)856);
            sb1.put((short)961);
 
            // print the ShortBuffer
            System.out.println("Original ShortBuffer: "
                               + Arrays.toString(sb1.array()));
 
            // print the ShortBuffer position
            System.out.println("\nposition: " + sb1.position());
 
            // print the ShortBuffer capacity
            System.out.println("\ncapacity: " + sb1.capacity());
 
            // Creating a shared subsequence buffer of given ShortBuffer
            // using slice() method
            ShortBuffer sb2 = sb1.slice();
 
            // print the shared subsequence buffer
            System.out.println("\nshared subsequence ShortBuffer: "
                               + Arrays.toString(sb2.array()));
 
            // print the ShortBuffer position
            System.out.println("\nposition: " + sb2.position());
 
            // print the ShortBuffer capacity
            System.out.println("\ncapacity: " + sb2.capacity());
        }
 
        catch (IllegalArgumentException e) {
 
            System.out.println("IllegalArgumentException catched");
        }
 
        catch (ReadOnlyBufferException e) {
 
            System.out.println("ReadOnlyBufferException catched");
        }
    }
}

Original ShortBuffer: [856, 961, 0, 0, 0, 0, 0, 0, 0, 0]

position: 2

capacity: 10

shared subsequence ShortBuffer: [856, 961, 0, 0, 0, 0, 0, 0, 0, 0]

position: 0

capacity: 8
