这篇文章告诉你如何使用java.nio缓冲区如ByteBuffer,CharBuffer,DoubleBuffer等创建缓冲区,可以使用allocate(int capacity)方法。每个缓冲区对象都有allocate(int capacity)方法。调用此方法时,您需要传递要创建的缓冲区的容量值。
package org.nhooo.example.nio; import java.nio.*; public class BufferAllocate { public static void main(String[] args) { ByteBuffer byteBuffer = ByteBuffer.allocate(64); CharBuffer charBuffer = CharBuffer.allocate(64); ShortBuffer shortBuffer = ShortBuffer.allocate(64); IntBuffer intBuffer = IntBuffer.allocate(64); LongBuffer longBuffer = LongBuffer.allocate(64); FloatBuffer floatBuffer = FloatBuffer.allocate(64); DoubleBuffer doubleBuffer = DoubleBuffer.allocate(64); } }
