What are alternatives to requires and exports and how do they compare?

        // Example: Using alternative approaches to requires and exports
        // Suppose the following module structure:
        // Module1 (no requires / exports)
        // Module2 (uses Module1)
        
        // Module1.java
        package com.example.module1;

        public class Module1 {
            public String greet() {
                return "Hello from Module1!";
            }
        }

        // Module2.java
        package com.example.module2;

        import com.example.module1.Module1;

        public class Module2 {
            public void useModule1() {
                Module1 module1 = new Module1();
                System.out.println(module1.greet());
            }
        }

        // Note: In this example, Module2 is directly using Module1 class without
        // defining modules in module-info.java. You can alternatively use a combined approach
        // with interfaces or provide services to manage dependencies.
