关于InputStream 求大神解释！！

public int read()rn throws IOException从此输入流中读取一个数据字节。如果没有输入可用，则此方法将阻塞。 rnrn指定者：rn类 InputStream 中的 readrn返回：rn下一个数据字节；如果已到达文件末尾，则返回 -1。 rnrn以前都用的是数组来读取的rnrn用read一个一个读取rnFileInputStream in = new FileInputStream(new File("f:/root2.class"));rn int len = 0;rn while(-1!=(len=in.read()))rn System.out.print(len);rn rn byte [] data = new byte[1024];rn FileInputStream in2 = new FileInputStream(new File("f:/root2.class"));rn while(-1!=(len=in2.read(data)))rn System.out.println();rn System.out.println(Arrays.toString(data));rn rnrn为啥用read（） 会返回的都是正数 而读到缓存数组中就会存在负值rn求大神解释
