Creating Your First Java Program

I’ll admit it’s not the most exciting program ever written, but you now know the steps every Java program has to go through:

1. Write the Java code in a text file
2. Save the file
3. Compile the source code
4. Fix any errors
5. Run the program

As the programs get more interesting, these steps will become second nature.
