Object Oriented Analysis & Design
How system analysis and design is different from object oriented analysis and design?
System analysis and design (SA&D) and object-oriented analysis and design (OOAD) are two different approaches to the development of computer-based information systems. SA&D is a traditional approach that focuses on understanding the requirements of the system, analyzing the current system, and designing a new system that meets those requirements. It is a process-oriented approach that typically involves creating a detailed specification of the system before beginning development. On the other hand, OOAD is a modern approach that focuses on modeling the system as a collection of objects that interact with each other to achieve the desired functionality. It is a more object-oriented approach that involves designing a system by first identifying the objects in the system, their properties, and the relationships between them. Some of the key differences between SA&D and OOAD are: Focus: SA&D focuses on the process of designing a system, while OOAD focuses on the objects in the system and their interactions. Design: SA&D is typically a top-down design approach, while OOAD is a bottom-up design approach. Requirements gathering: SA&D emphasizes the gathering of requirements and creating detailed specifications before beginning development, while OOAD emphasizes rapid prototyping and iterative development. Abstraction: OOAD relies heavily on abstraction, while SA&D relies more on specific details and processes. Overall, both SA&D and OOAD are valid approaches to the development of computer-based information systems, and the choice between them depends on the specific needs and requirements of the project.
What is the Object class parent?
Object is the topmost class in the Java Class hierarchy. There is no Class above Object. All classes in Java are implicitly derived from Object.
What class is the super class for ALL Java classes?
The Object class, in the java.lang package, sits at the top of the class hierarchy tree. Every class is a descendant, direct or indirect, of the Object class. Every class you use or write inherits the instance methods of Object. You need not use any of these methods, but, if you choose to do so, you may need to override them with code that is specific to your class
What is class hierarchies in java?
The top level class in Java is class Object. Every other class inherits from Object and therefore Object is the top most in the class hierarchy. If you extend a class from Object such as class Animal and further extend Animal with class Dog then the hierarchy is as follows: Object | Animal | Dog Code for this hierachy is as follows: class Animal { } class Dog extends Animal { } We don't need to write class Animal extends Object because every class extends from Object so it does not need to be stated.

Object Oriented Analysis & Design
What is dependency in ooad?
In object-oriented analysis and design (OOAD), dependency represents a relationship between classes where one class relies on another in some way. This reliance can be in the form of one class using services or attributes of another class, or passing instances of one class as arguments to methods in the other class. Dependencies are established through instantiation, method calls, or passing parameters, and they are denoted with a dotted arrow in UML class diagrams.
How is UML related to OOAD?
UML supports Object Oriented Analysis and Design (OOAD). It has all related concepts like classes, objects, inheritance, encapsulation, polymorphism, etc. UML is most suitable for use case driven, iterative and incremental development processes as most OOAD processes are.
