What is the use of BufferedReader in Java programming?
The BufferedReader class provides buffering to your Reader's. Buffering can speed up IO quite a bit. Rather than read one character at a time from the network or disk, you read a larger block at a time. This is typically much faster, especially for disk access and larger data amounts. The main difference between BufferedReader and BufferedInputStream is that Reader's work on characters (text), wheres InputStream's works on raw bytes. To add buffering to your Reader's simply wrap them in a BufferedReader. Here is how that looks: Reader input = new BufferedReader( new FileReader("c:\\data\\input-file.txt"));
What is meaning for BufferedReader br equals new BufferedReader new InputStreamReade System in?
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));This line will create a new BufferedReader object, which reads from System.in (standard input). The InputStreamReader part is used to convert System.in (which is an InputStream) to a Reader object (which can be used by BufferedReader).After creating br, you can read input from the user:String input = br.readLine();The line above will allow the user to type in anything they want, press the button, and have what they typed in stored in input.
What is BufferedReader in java?
in java buffering is used for handling i/o streamswhen you use an unbuffered stream the data is directly transferred from the source to whatever.when you use buffered stream the data is taken from the source and placed into something like a holding area. then the information can be taken from this holding area at will which makes buffered streams more efficient.for example when you load a vid on youtube once part of it loads you can use play anypart of the loaded vid. that's not exactly how it works but it gives you a general sense.

What is BufferedReader in Java Programming?
BufferedReader is a class used to read text from charater-input stream and buffering characters which reads characters, arrays, and new lines. In general, each read request made using "Reader" class, causes a corresponding read request to be made of the underlying character or byte stream. It is therefore advisable to wrap a BufferedReader around any Reader whose read() operations may be costly, such as FileReaders and InputStreamReaders. For example, BufferedReader in = new BufferedReader(new FileReader("foo.in"));
