Console Programs allow for interaction between your program and the user. In order to write a program, make sure your program extends ConsoleProgram:
public class Example extends ConsoleProgram {

One cool thing that Console Programs let you do is get input from the user. Below are some examples:
readLine(String promptMessage); //Reads a String from the user and return it
readInt(String promptMessage); //Reads an int from the user and return it
readDouble(String promptMessage); //Reads a double from the user and return it
println(String printMessage); //Prints a message to the Console
