如果您的Java程序中,使用BufferedReader的read(byte[])方法时出现了Cannot resolve method 'read(byte[])'错误,可能是因为BufferedReader没有该方法。BufferedReader的read()方法只能读取单个字符或一行文本。如果您需要读取字节,请使用InputStream或InputStreamReader。
以下是使用InputStream读取字节的示例代码:
```
InputStream inputStream = new FileInputStream("path/to/file");
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = inputStream.read(buffer)) != -1) {
// 处理读取到的字节
}
inputStream.close();
```
如果您需要将字节转换为字符,请使用InputStreamReader:
```
InputStream inputStream = new FileInputStream("path/to/file");
Reader reader = new InputStreamReader(inputStream);
char[] buffer = new char[1024];
int bytesRead;
while ((bytesRead = reader.read(buffer)) != -1) {
// 处理读取到的字符
}
reader.close();
```
