java - BufferedReader直接转byte[]

Question

我下面的 BufferedReader 是否有可能将输入直接放入 byte[]？

public static Runnable reader() throws IOException {
    Log.e("Communication", "reader");
    din = new DataInputStream(sock.getInputStream());
    brdr = new BufferedReader(new InputStreamReader(din), 300);
    boolean done = false;
    while (!done) {
       try {
       char[] buffer = new char[200];
           int length = brdr.read(buffer, 0, 200);
           String message = new String(buffer, 0, length);
           btrar = message.getBytes("ISO-8859-1");                      
           int i=0;
           for (int counter = 0; counter < message.length(); counter++) {
              i++;  
              System.out.println(btrar[counter] + " = " + " btrar "  + i);
           }
    ...

这就是读者的部分，请看

我想直接输入btrar，

Answer 1

is there any possibility my following BufferedReader is able to put the input directly into a byte[]?

任何 Reader 都旨在让您阅读字符，而不是字节。要读取二进制数据，只需使用 InputStream - 如果需要，可以使用 BufferedInputStream 对其进行缓冲。

不太清楚您要做什么，但您可以使用类似的东西:

BufferedInputStream input = new BufferedInputStream(sock.getInputStream());
while (!done) {
    // TODO: Rename btrar to something more meaningful
    int bytesRead = input.read(btrar);
    // Do something with the data...
}
