This chapter is from the book


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 four basic steps:

  1. Write the program with a text editor or a tool such as NetBeans.
  2. Compile the program into a class file.
  3. Tell the Java Virtual Machine to run the class.
  4. Call your mother.

Along the way, you were introduced to some basic computer programming concepts such as compilers, interpreters, blocks, statements, and variables. These 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.

(The fourth step has nothing to do with Java programming. It’s just something my mother suggested I put in the book.)
