Let’s learn about a few ways of reading data from files into a byte array in Java. 1. UsingFiles.readAllBytes() TheFiles.readAllBytes()is the best method for using Java 7, 8 and above. It reads all bytes from a file and closes the file. The file is also closed on an I/O err...
接下来,我们需要将文件内容转换为字节数组。可以使用ByteArrayOutputStream来实现。代码如下所示: // 转换为字节数组ByteArrayOutputStreambos=newByteArrayOutputStream();byte[]buffer=newbyte[1024];intlen;while((len=fis.read(buffer))!=-1){bos.write(buffer,0,len);}byte[]data=bos.toByteArray(); 1....

The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This read method cannot block. Java documentation for java.io.ByteArrayInputStream.read(). Portions of this page are ...
// 从“数据输入流”中读取数据并存储到字节数组bytearr中;从bytearr的位置0开始存储,存储长度为utflen。 // 注意,这里是存储到字节数组!而且读取的是全部的数据。 in.readFully(bytearr, 0, utflen); // 将“字节数组bytearr”中的数据 拷贝到 “字符数组chararr”中 ...
