obtener()
El método get() de java.nio.IntBuffer Class se usa para leer el int en la posición actual del búfer dado y luego incrementa la posición.
Sintaxis:
public abstract int get()
Valor devuelto: este método devuelve el valor int en la posición actual del búfer.
Lanza: este método lanza BufferUnderflowException : si la posición actual del búfer no es más pequeña que su límite, se lanza esta excepción.
A continuación se muestran los ejemplos para ilustrar el método get():
Ejemplos 1:
// Java program to demonstrate // get() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the IntBuffer int capacity = 5; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(8); ib.put(9); ib.put(1); ib.rewind(); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at this buffer's current position // using get() method int value = ib.get(); // print the Int value System.out.println("Int Value: " + value); // Reads the Int at this buffer's next position // using get() method int value1 = ib.get(); // print the Int value System.out.print("Next Int Value: " + value1); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("ReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("Exception throws: " + e); } } }
Original IntBuffer: [8, 9, 1, 0, 0] Int Value: 8 Next Int Value: 9
Ejemplos 2: Para demostrar java.nio.BufferUnderflowException
// Java program to demonstrate // get() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the IntBuffer int capacity = 3; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(8); ib.put(9); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at this buffer's current position // using get() method int value = ib.get(); // print the Int value System.out.println("Int Value: " + value); // Reads the Int at this buffer's next position // using get() method System.out.print("Since the buffer current position is incremented"); System.out.print(" to greater than its limit "); int value1 = ib.get(); // print the Int value System.out.print("Next Int Value: " + value1); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (ReadOnlyBufferException e) { System.out.println("ReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("Exception throws : " + e); } } }
Original IntBuffer: [8, 9, 0] Int Value: 0 Since the buffer current position is incremented to greater than its limit Exception throws : java.nio.BufferUnderflowException
obtener (índice int)
El método get(int index) de IntBuffer se usa para leer el artículo en un índice específico.
Sintaxis:
public abstract int get(int index)
Parámetros: este método toma el índice (el índice desde el cual se leerá el int) como parámetro.
Valor devuelto: este método devuelve el valor int en el índice dado.
Excepción: este método genera una excepción IndexOutOfBoundsException . Si el índice es negativo o no menor que el límite del búfer, se lanza esta excepción.
A continuación se muestran los ejemplos para ilustrar el método get(int index):
Ejemplos 1:
// Java program to demonstrate // get(int index) method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the IntBuffer int capacity = 3; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(8); ib.put(9); ib.put(6); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at the index 0 of the Intbuffer // using get() method int value0 = ib.get(0); // print the Int value System.out.println("Int Value at index 0: " + value0); // Reads the Int at the index 1 of the Intbuffer // using get() method int value1 = ib.get(1); // print the Int value System.out.println("Int Value at index 1: " + value1); // Reads the Int at the index 2 of the Intbuffer // using get() method int value2 = ib.get(2); // print the Int value System.out.println("Int Value at index 2: " + value2); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (IndexOutOfBoundsException e) { System.out.println("ReadOnlyBufferException catched"); } catch (BufferUnderflowException e) { System.out.println("Exception throws : " + e); } } }
Original IntBuffer: [8, 9, 6] Int Value at index 0: 8 Int Value at index 1: 9 Int Value at index 2: 6
Ejemplos 2: Para demostrar IndexOutOfBoundsException
// Java program to demonstrate // get() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // Declaring the capacity of the IntBuffer int capacity = 3; // Creating the IntBuffer try { // creating object of Intbuffer // and allocating size capacity IntBuffer ib = IntBuffer.allocate(capacity); // putting the value in Intbuffer ib.put(6); ib.put(8); ib.put(12); // print the IntBuffer System.out.println("Original IntBuffer: " + Arrays.toString(ib.array())); // Reads the Int at the index 0 of the Intbuffer // using get() method int value0 = ib.get(0); // print the Int value System.out.println("Int Value at index 0: " + value0); // Reads the Int at the index 1 of the Intbuffer // using get() method int value1 = ib.get(1); // print the Int value System.out.println("Int Value at index 1: " + value1); // Reads the Int at the index 2 of the Intbuffer // using get() method System.out.println("Trying to get the Int" + " of index greater than its limit "); int value2 = ib.get(4); // print the Int value System.out.println("Int Value at index 2: " + value2); } catch (IllegalArgumentException e) { System.out.println("IllegalArgumentException catched"); } catch (IndexOutOfBoundsException e) { System.out.println("Exception thrown: " + e); } catch (BufferUnderflowException e) { System.out.println("Exception throws : " + e); } } }
Original IntBuffer: [6, 8, 12] Int Value at index 0: 6 Int Value at index 1: 8 Trying to get the Int of index greater than its limit Exception thrown: java.lang.IndexOutOfBoundsException
