Development Environment Check: Java Execution

Due Wednesday before class

Objective

to confirm that you can compile Java program files and execute the classes.

Practice on a Given Program

If you haven't already, set up your computer for Java development.

• Create a new directory with the directory that you're using for this class, e.g., practice
• Download First.java and save it in your practice directory.
• In your terminal, navigate to your practice directory.
• Compile and run First.java:
  • javac First.java
    Compiles the program into First.class
    List the contents of your directory to see First.class
  • java First
    Runs the JVM, which executes the bytecode
• View First.java in your favorite text editor, e.g., if your text editor is jEdit, you'd run
  jedit First.java &.
• Review the components of the program. Make sure you understand why the code outputs what it does.

Submitting your assignment
