obtener()
El método get() de java.nio.FloatBuffer Class se usa para leer el flotante en la posición actual del búfer dado y luego incrementa la posición.
Sintaxis:
public abstract float get()
Valor devuelto: este método devuelve el valor flotante 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 FloatBuffer
int capacity = 5;
// Creating the FloatBuffer
try {
// creating object of floatbuffer
// and allocating size capacity
FloatBuffer fb = FloatBuffer.allocate(capacity);
// putting the value in floatbuffer
fb.put(8.56F);
fb.put(9.61F);
fb.put(1.24F);
fb.rewind();
// print the FloatBuffer
System.out.println("Original FloatBuffer: "
+ Arrays.toString(fb.array()));
// Reads the float at this buffer's current position
// using get() method
float value = fb.get();
// print the Float value
System.out.println("\nFloat Value: " + value);
// Reads the float at this buffer's next position
// using get() method
float value1 = fb.get();
// print the Float value
System.out.print("\nNext Float Value: " + value1);

obtener (índice int)
El método get(int index) de FloatBuffer se usa para leer el artículo en un índice específico.
Sintaxis:
public abstract float get(int index)
Parámetros: este método toma el índice (el índice del que se leerá el flotante) como parámetro.
Valor devuelto: este método devuelve el valor flotante 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.
