在Java中当我们要对数据进行更底层的操作时，一般是操作数据的字节（byte）形式，这时经常会用到ByteBuffer这样一个类。ByteBuffer提供了两种静态实例方式：

    public static ByteBuffer allocate(int capacity)  public static ByteBuffer allocateDirect(int capacity)

为什么要提供两种方式呢？这与Java的内存使用机制有关。第一种分配方式产生的内存开销是在JVM中的，而另外一种的分配方式产生的开销在JVM之外，以就是系统级的内存分配。当Java程序接收到外部传来的数据时，首先是被系统内存所获取，然后在由系统内存复制复制到JVM内存中供Java程序使用。所以在另外一种分配方式中，能够省去复制这一步操作，效率上会有所提高。可是系统级内存的分配比起JVM内存的分配要耗时得多，所以并非不论什么时候allocateDirect的操作效率都是最高的。以下是一个不同容量情况下两种分配方式的操作时间对照：

由图能够看出，当操作数据量非常小时，两种分配方式操作使用时间基本是同样的，第一种方式有时可能会更快，可是当数据量非常大时，另外一种方式会远远大于第一种的分配方式。

导致以下错误的原因在于：
JNI调用C方法自然是使用系统内存。
public static ByteBuffer allocate(int capacity)方法在JVM创建的缓冲区C方法是读不到的。
所以必须使用
public static ByteBuffer allocateDirect(int capacity)在系统内存中操作我们的数据。
正式由于C方法读不到JVM中的我们写入的数据，才会导致报jarray was NULL
