Recently, learning Java, and learning about Java IO (input and input), what is Java IO?IO flow is located in the Java.io packet, according to the operation data, divided into byte stream and character stream, according to different data input and can be divided into the input stream and

It can also be used to communicate byte processing streams and character processing streams. As follows:BufferedReader in=new BufferedReader (New InputStreamReader (New FileInputStream ("File.tax"), "UTF-8"); It's just a s

For a general amplifying circuit, the smaller the output resistance, the better.Current amplification and mutual guide amplification circuit, that is, the current signal amplification circuit, the larger the RO parallel with the controlled current source, the less the load RL changes on the
