	// 1. Data
	// 2. Subroutines (methods)
}


public class App {

	public static void main(String[] args) {
		
		
		// Create a Person object using the Person class
		Person person1 = new Person();	
		person1.name = "Joe Bloggs";
		person1.age = 37;
		
		// Create a second Person object
		Person person2 = new Person();
		person2.name = "Sarah Smith";
		person2.age = 20;
		
		System.out.println(person1.name);
		
	}
