Command-line arguments are a common way to parameterize execution of programs. For example, java MyProgram arg1 arg2 uses arg1 and arg2 as arguments to the MyProgram class.
To experiment with command-line arguments, it’s best to compile the Java program first.
Next, we’ll look at more advanced command-line processing with flags. In Java, this is typically done using libraries like Apache Commons CLI or Picocli.
