Some Simple Graphics

Yes.... we can do some simple graphics without having to spend a month learning the whole Java graphics system.
There are two things that we can do easily ...

Unicode characters

You can also add unicode characters using escape codes.
System.out.println("I am the \u265B \u2394");

which prints out like I am the ♛ ⎔  

READ THIS:

• Syntax: \u _ _ _ _ Write 4 digits after the \u. They are hexadecimal (and so can include A-F)
• This website has a great list of unicode characters
• Unicode is pretty complicated. I don't do anything more complex than this.
• Java can only have FOUR numbers after \u. That means that you can never display many emojis like \u1F601 🚉
• Some computers won't display certain symbols, depending on what fonts have been loaded.

JOptionPane

We can make pop up text boxes which are called JOptionPanes (most graphic classes in Java start with the letter J)

Copy this code into NotePad++ and save it as OptionPane.java . Once you save it, it will be a WHOLE lot easier to read as it will have syntax colouring.
