Somewhat to my surprise, the following code prints out "Close" twice.

I have a function that takes an object of a certain type, and a PrintStream to which to print, and outputs a representation of that object. How can I capture this function's output in a String? Specifically, I want to use it as in a toString method. ...

This package is ultimately accessed through a single function and sends all of its output through a PrintStream object.

I was looking at someone's code and saw that he repeatedly declared PrintStream out = System.out; and later called out.println("blah"); I actually thought this was kind of neat. Is this a common practice? Was he just being fancy? ...

I am attempting to make a Java program in which a user can select any .class or .jar file from their computer. My program will then pop up a JInternalFrame with a JEditorPane in it as the console, capturing any console output from the user's program.
