其中,readAllBytes方法可以一次性读取文件的所有字节,返回一个字节数组。示例代码如下: 代码语言:txt 复制 try { byte[] fileBytes = Files.readAllBytes(Paths.get("file.txt")); // 对文件字节数组进行操作 } catch (IOException e) { // 处理异常 } 使用Buffere...
= null) { System.out.println("Detected charset: " + encoding); // 使用检测到的编码重新读取文件 String content = new String(Files.readAllBytes(Paths.get(file.toURI())), Charset.forName(encoding)); System.out.println(content); } else { System.out.println("Detection failed."); } } ...
