Can I peek on a BufferedReader?

Is there a way to check if in BufferedReader object is something to read? Something like C++ cin.peek(). Thanks.

Solution

  • You can try the "boolean ready()" method. From the Java 6 API doc: "A buffered character stream is ready if the buffer is not empty, or if the underlying character stream is ready."

    BufferedReader r = new BufferedReader(reader);
if(r.ready())
{
   r.read();
}
