During this hour, you got your first chance to create a Java program. You learned that to develop a Java program you need to complete these three basic steps:
Write the program with a word processor.
Compile the program into a class file.
Tell the interpreter to run the class.
Along the way, you were introduced to some basic computer programming concepts such as compilers, interpreters, blocks, statements, and variables. These things will become clearer to you in successive hours. As long as you got the Saluton program to work during this hour, you're ready to proceed.
