In this tutorial, we will see how to transfer the content of a long buffer into another long buffer.

LongBufferAPI:

The java.nio.LongBuffer class extends java.nio.Buffer class. It provides the following methods:

Return type	Method	Description
static LongBuffer	allocate(int capacity)	The allocate(..)method allocate a new long buffer.
LongBuffer	put(LongBuffer buffer)	The put(..)method transfer the content of a long buffer into another long buffer.

Code


import java.nio.*;

import java.nio.LongBuffer;



public class TransferBufferValue {

  public static void main(String[] args) {

    long[] arr = new long[] { 345553322, 22332434, 575876433 };

    LongBuffer longBuf = LongBuffer.wrap(arr);

    System.out.println("Value in buffer.");

    for (int i = 0; i < longBuf.limit(); i++) {

      System.out.println(longBuf.get());

    }

    longBuf.flip();

    LongBuffer longBuffer1 = LongBuffer.allocate(124);

    longBuffer1.put(longBuf);

    longBuffer1.flip();

    System.out

    .println("After transfer a long buffer value into another buffer.");

    System.out.println("Value in new long buffer.");

    for (int i = 0; i < longBuf.limit(); i++) {

      System.out.println(longBuffer1.get());

    }

  }

}

Output

C:\>java TransferBufferValue
Value in buffer.
345553322
22332434
575876433
After transfer a long buffer value into another buffer.
Value in new long buffer.
