- Standard input/console input
  - Method of obtaining input via the console
- System.in
  - The object used to perform standard input
  - Instance of InputStream class
  - Can only read one byte at a time
- InputStreamReader
  - Read a single character at a time
- BufferedReader
  - Read a single line that consists of multiple characters at a time
  - Associate with System.in:
    import java.io.*;
    ...
    BufferedReader bufReader;
    bufReader = new BufferedReader( new InputStreamReader(System.in) );
  - readLine method
    - Reads until the Enter key is pressed
    - No visual cue of expectation automatically provided
    - Echo printing: Standard output window echoes input characters back to user
    - Can erase characters before pressing Enter via the backspace key
    - By default returns a String
      - Must use wrapper classes to parse into other data types
- Exception: error condition
  - Magic for now
  - Must add "throws IOException" to any method using the readLine method
    - By doing this in the method declaration, pass on handling to the system
  - Instance of IOException class represents IO exception
  - Will cause a compiler error if you don't handle it in some way
- Method has thrown an exception when executing it causes an exception

Quick Check:
1. int height;
   String input;
   BufferedReader bufReader;
   bufReader = new BufferedReader( new InputStreamReader( System.in ) );
   System.out.print("Enter your height in inches: ");
   input = bufReader.readLine();
   height = Integer.parseInt(input);
2. double weight;
   String input;
   BufferedReader bufReader;
   bufReader = new BufferedReder( new InputStreamReader( System.in ) );
   System.out.print("Enter your weight in pounds: ");
   input = bufReader.readLine();
   weight = Integer.parseInt(input);
   weight = weight * 453.592 / 1000;
   System.out.println("You weigh " + weight + "kilograms.");
