我们需要确保实体类实现了Serializable接口,例如: publicclassPersonimplementsSerializable{// 属性和方法省略} 1. 2. 3. 然后,我们可以使用java.io.ObjectOutputStream类将对象序列化为字节数组。下面是进行对象序列化的代码: ByteArrayOutputStreambos=newByteArrayOutputStream();ObjectOutputStreamoos=newObjectOutputStre...

AByteArrayInputStreamcontains an internal buffer that contains bytes that may be read from the stream. An internal counter keeps track of the next byte to be supplied by thereadmethod. Closing aByteArrayInputStreamhas no effect. The methods in this class can be called after the...
一、ByteArrayOutputStream流定义 API说明:此类实现一个字节输出流、其中数据被写入到字节数组中, 缓冲区在数据写入时会自动增长,关闭该流无效,关闭此流后调用方法不会有异常 二、ByteArrayOutputStream流实例域 /** * 存储数据的缓冲区 */ protected byte buf[]; ...
