Input syntax?
Quick question. What is the "default" syntax for input from a screen (take information from the screen and place it into a variable, etc..). For example, I have the SavitchIn class that contains input methods such as:
SavitchIn.readLine(); // Gets data from a line on the screen SavitchIn.readLineInt(); // Gets an interger from a line on the screen Thank you in advance  |

BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String s = in.readLine(); |

For input like above, you have to import java.io.BufferedReader and java.io.InputStreamReader. The input will come in as a String. If you want it to be an integer, you have to change it with this:
int i = Integer.parseInt(s); To use this method, you have to import java.lang.Integer. |

So, to cover all the bases and to allow a program to be run on all PCs, would be to stick the following at the top (well, in the right area..
 ):import java.io.* BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); After that, I would just have to cast the String to whatever I would need. Doesn't java automatically import the java.lang.* ? Thanks |

BufferedReader is probably what you'll see most often, but I personally feel the Scanner class is much easier to use. I would certainly take a look into that.
