Lesson 1 -- if, else

if

If the program says

if (name.equals("kangaroo")) {
  System.out.println("You live in Australia!"); 
}

then if the name is "kangaroo", the Australia message will be displayed.

if/else

If the program says

if (name.startsWith("q")) {
  System.out.println("Your name starts with q -- how unusual!"); 
} else {
  System.out.println("Your name starts with a non-q letter"); 
}

people with names starting with 'q' get a special message, everyone else is told they have a non-q letter.

Problems

Have the program print out a special welcome message like 'Good luck' for people with your name, but the normal welcome message for everyone else.
Have the program give you the same number every time so you have an easy time guessing.
