InputReader can covert bytes in different encodings to characters.
BufferedReader has a back-end reader which speeds up reading if you are only retrieving small parts at a time.
BufferedReader can mark a given position, and after already reading the bytes, reset back to the previous position.

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 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"));
How do you write a program that takes a list of all positive integers from input and counts as the integers are input?
// create an BufferedReader from the standard input stream BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String currentLine = ""; int total = 0; // read integers System.out.print("Input an integer: "); while (!(currentLine = in.readLine()).equals("")) { int input = 0; try { input = Integer.valueOf(currentLine); total += input; } catch (final NumberFormatException ex) { System.out.println("That was not an integer."); } System.out.print("Input an integer: "); }
How do you find odd numbers between two numbers in java?

What is the difference between datainputstream and bufferedreader?
The differences are: The DataInputStream works with the binary data, while the BufferedReader work with character data. All primitive data types can be handled by using the corresponding methods in DataInputStream class, while only string data can be read from BufferedReader class and they need to be parsed into the respective primitives. DataInputStream is a part of filtered streams, while BufferedReader is not. DataInputStream consumes less amount of memory space being it is binary stream, where as BufferedReader consumes more memory space being it is character stream. The data to be handled is limited in DataInputStream, where as the number of characters to be handled has wide scope in BufferedReader.
