CSC152 2005S, Class 7: More Text-based Input and Output

Admin
* Reading for tomorrow: "Strings in Java"
* Bounty remains (and I'm sorry for the pages that work incorrectly).
* Picnic signup!
* Please work in pairs!
* Apologies: Java is pretty much "just do it this way" right now

Overview:
* Questions from last class?
* Lab
* Reflection (maybe)

Some problems from last class
* Need to declare names (variables) before you use them
	pen.println(userinput)
  won't work unless you've previously written
  	String userinput;
	userinput = ...
	PrintWriter pen;
	pen = ...;
* The order in which you perform operations is important
	userinput = eyes.readLine();
	pen.print("Please enter your name: ");
	pen.flush();
* Some design decisions in Java are STUPID
	file.println("Hello");
	// end program
  May not put anything in the file
  So you need to flush!
* Capitalization matters (and is, unfortunately, inconsistent)
  * Classes use mixed case and begin with uppercase letters 
    (new uppercase letter = new word)
  * Methods use mixed case and begin with lowercase letters 

Some lessons:
* Java lets you overwrite files w/o complaining.
* Java does not let you write to other people's directories
