El método duplicate() de java.nio.IntBuffer Class se usa para crear un nuevo IntBuffer que comparte el contenido del búfer dado, de manera idéntica en todos los aspectos.
Sintaxis:
public abstract IntBuffer duplicate()
Valor de retorno: este método devuelve el nuevo IntBuffer que lleva el contenido del IntBuffer anterior
A continuación se muestran los ejemplos para ilustrar el método duplicate() :
Ejemplos 1: uso directo de IntBuffer
// Java program to demonstrate duplicate() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the IntBuffer int capacity = 10; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib1 = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib1.put(8); ib1.put(2, 9); ib1.rewind(); // print the Original IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib1.array())); // Creating a duplicate copy of IntBuffer // using duplicate() method IntBuffer ib2 = ib1.duplicate(); // print the duplicate copy of IntBuffer System.out.print("Duplicate IntBuffer: " + Arrays.toString(ib2.array())); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("ReadOnlyBufferException catched"); } } }
Producción:
Original IntBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0] Duplicate IntBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0]
Ejemplos 2: Usar intbuffer de solo lectura
// Java program to demonstrate // duplicate() method // using read-onlyIntbuffer import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the IntBuffer int capacity = 10; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib1 = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib1.put(8); ib1.put(2, 9); ib1.rewind(); // print the Original IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib1.array())); // Creating a read-only copy of IntBuffer // using asReadOnlyBuffer() method IntBuffer readonly = ib1.asReadOnlyBuffer(); // print the read-only copy of IntBuffer System.out.print("read-only IntBuffer: "); while (Readonly.hasRemaining()) System.out.print(readonly.get() + ", "); System.out.println(""); // Rewinding the readonly IntBuffer readonly.rewind(); // Creating a duplicate copy of IntBuffer // using duplicate() method IntBuffer ib2 = readonly.duplicate(); // print the duplicate copy of IntBuffer System.out.print("Duplicate copy of read-only IntBuffer: "); while (ib2.hasRemaining()) System.out.print(ib2.get() + ", "); System.out.println(""); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("ReadOnlyBufferException catched"); } } }
Producción:
Original IntBuffer: [8, 0, 9, 0, 0, 0, 0, 0, 0, 0] Read-only IntBuffer: 8, 0, 9, 0, 0, 0, 0, 0, 0, 0, Duplicate copy of read-only IntBuffer: 8, 0, 9, 0, 0, 0, 0, 0, 0, 0,
