    public String getName() {
        return this.name;
    }
    public void setName(String name) {
        this.name= name;
    }
}
public class Accessesdpps {
    public static void main(String[] main){
        Royal d = new Royal();
        d.setName("Basic Engineer");
        System.out.println(d.getName());
    }
}
