If you would like to explore the topics covered in this hour a little more fully, try the following activities:

  • You can translate the English phrase "Hello world!" into other languages using the AltaVista website Babelfish, located at Write a program that enables your computer to greet the world in a language such as French, Italian, or Portuguese.
  • Go back to the Saluton program and add one or two errors. For example, take a semicolon off the end of a line, or change the text println on one line to print1n. Save the program and try to compile it. Compare the error messages you get to the errors you caused.
