El método get() de java.nio.DoubleBuffer Class se usa para leer el doble en la posición actual del búfer dado y luego incrementa la posición.
Sintaxis:
public abstract double get()
Valor devuelto: este método devuelve el valor doble en la posición actual del búfer.
Excepción: este método lanza BufferUnderflowException si la posición actual del búfer no es más pequeña que su límite, entonces 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
DoubleBuffer fb
= DoubleBuffer.allocate(capacity);
// putting the value in Doublebuffer
fb.put(8.56D);
fb.put(9.61D);
fb.put(1.24D);
fb.rewind();
// print the DoubleBuffer
System.out.println("Original DoubleBuffer: "
+ Arrays.toString(fb.array()));
// Reads the double at this buffer's current position
// using get() method
double value = fb.get();
// print the double value
System.out.println("\nDouble Value: "
+ value);
// Reads the double at this buffer's next position
// using get() method
double value1 = fb.get();
// print the double value
System.out.print("\nNext double Value: " + value1);
}
catch (IllegalArgumentException e) {
System.out.println("\nIllegalArgumentException catched");
}
catch (ReadOnlyBufferException e) {
System.out.println("\nReadOnlyBufferException catched");
}
catch (BufferUnderflowException e) {
System.out.println("\nException throws: " + e);
}
}
}
Producción:
Original DoubleBuffer: [8.56, 9.61, 1.24, 0.0, 0.0] Double Value: 8.56 Next double Value: 9.61
Ejemplos 2:
// 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 DoubleBuffer

// and allocating size capacity
DoubleBuffer fb = DoubleBuffer.allocate(capacity);

// print the Double value
System.out.println("\nDouble Value: " + value);
// Reads the Double at this buffer's next position
// using get() method
System.out.print("\nsince the buffer current"
+ " position is incremented");
System.out.print(" to greater than its limit ");
Double value1 = fb.get();
// print the Double value
System.out.print("\nNext Double Value: " + value1);
}
catch (IllegalArgumentException e) {
System.out.println("\nIllegalArgumentException catched");
}
catch (ReadOnlyBufferException e) {
System.out.println("\nReadOnlyBufferException catched");
}
catch (BufferUnderflowException e) {
System.out.println("\nException throws: " + e);
}
}
}
Producción:
Original DoubleBuffer: [8.5600004196167, 9.609999656677246, 0.0] Double Value: 0.0 since the buffer current position is incremented to greater than its limit Exception throws: java.nio.BufferUnderflowException
