位于java.io包下 官方对其说明: This class implements an output stream in which the data is written into a byte array. The buffer automatically grows as data is written to it. The data can be retrieved using toByteArray() and toString(). (简单翻译:ByteArrayInputStream实现了一个输出流,其中...

ByteArrayOutputStream实现了一个输出流,其中的数据被写入一个 byte 数组。缓冲区会随着数据的不断写入而自动增长。可使用 toByteArray()和 toString()获取数据。 1.1 方法介绍 ByteArrayInputStream提供的API如下: // 构造函数 ByteArrayInputStream(byte[] buf) ByteArrayInputStream(byte[] buf, int offset, in...

In this article, you'll learn how to convert an InputStream object to a String in Java using different Java APIs and a 3rd-party library — Apache Commons IO. Convert an InputStream to a string using InputStream.readAllBytes() Since Java 9, you can use the readAllBytes() method from ...

ByteArrayInputStream和ByteArrayOutputStream 内存虚拟文件或者内存映像文件就是把内存中的一块数据存储缓冲区,虚拟成一个文件,原来该写入硬盘文件上的内容可以被写入到这个内存中,原来该从硬盘文件中读取的内容也可以在内存中读取。 而要在内存中定义一个大的内存缓冲区,这个内存缓冲区通常就是一个字节数组,在java中...
