What steps should I follow to compile and run Java files?

Step-by-Step Guide:

To compile and run Java files from the command prompt, follow these steps:

1. Open the command prompt and navigate to the directory where your Java files are located. In this case, navigate to the directory c:\\Code\\com\\CITC1318\\course.

2. Compile the Java files using the javac command. Run the following command to compile all the Java files in the directory:

javac com/CITC1318/course/GreetingsClass.java com/CITC1318/course/chapters/*.java

This command compiles the GreetingsClass.java file and all the Java files in the chapters package.

3. Make sure that you have Java installed and the javac command is in your system's PATH.

4. After successful compilation, .class files will be generated in the same directory.

5. Now, run the Java program using the java command. Run the following command:

java com.CITC1318.course.GreetingsClass

This command runs the GreetingsClass program and you should see the output on the command prompt.

6. If you encounter the error "package com.citc1318.course.chapters does not exist" and "error: cannot find symbol," ensure that the file structure and package names are consistent and correct. Check for any typos in the package names and ensure that the file names match the class names exactly.
