import java.nio.ByteBuffer;

public class GetIntBuffer {

  public static final int capacity = 100;

public static void main(String[] argv) throws Exception{

    ByteBuffer bytebuf = ByteBuffer.allocate(capacity);

    bytebuf.putInt(221255);

    bytebuf.flip();

System.out.println("Integer data into byte buffer : "

        + bytebuf.getInt());

  }

}
