Check for number of elements exists between the current position and the limit of a double type buffer.

In this tutorial you will see how to check for existence of any element between the current position and the limit of a double buffer. The remaining method returns the number of element available in a buffer.

Code:

import java.nio.DoubleBuffer;

public class DoubleBufferDemo {
  public static void main(String[] args) {
    double[] db1 = new double[] {};
    DoubleBuffer buffer1 = DoubleBuffer.wrap(db1);
    buffer1.put(db1);
    System.out.println(buffer1.remaining());
    double[] db2 = new double[] { 2325.54 };
    DoubleBuffer buffer2 = DoubleBuffer.wrap(db2);
    buffer2.put(db1);
    System.out.println(buffer2.remaining());
  }
}

Output:
