You do not need to install any software to work on these exercises, all you need is a modern browser preferably Firefox, Chrome, or Safari.
The weekly assignments and final exam consist of multiple choice and multiple answer tests and debugging exercises. In the debugging exercises, we will provide a piece of code and you have to find the hidden bugs. We will have weekly assignments in weeks 1 to 5. The learning content of these weeks will also be part of the final exam. There will be no weekly assignments in the Intro, Outro, and Excursus in week 2. These three sections will also not be part of the final exam.
In week 4, we will offer a team-based modeling exercise. This exercise will be peer graded. The available bonus points correspond to the weekly assignment points of one and a half weeks. To participate in this course, all you need is to be interested in programming. Objektorientierte Programmierung in Java March 27 through May 14, Der Kurs wurde mit durchschnittlich 4.
In der Vergangenheit hat sie bereits auf vielseitige Art an mehreren Spiel-Projekten mitgewirkt. Sie hat als Softwareentwicklerin bei openWHO. Ein besonderer Schwerpunkt liegt auf der Zusammenarbeit und Interaktion unter den Kursteilnehmern, sowie Tools zur Leistungserfassung jenseits der klassischen Multiple-Choice Aufgaben. Insbesondere das Erlernen von neuen Programmiersprachen und Konzepten sowie die Potentiale und Auswirkungen von Interaktion zwischen den Lernenden sind im besonderen Fokus.
Some of these commonly occurring problems have implications and solutions particular to object-oriented development. It is intuitive to assume that inheritance creates a semantic " is a " relationship, and thus to infer that objects instantiated from subclasses can always be safely used instead of those instantiated from the superclass.
This intuition is unfortunately false in most OOP languages, in particular in all those that allow mutable objects. Subtype polymorphism as enforced by the type checker in OOP languages with mutable objects cannot guarantee behavioral subtyping in any context.

Behavioral subtyping is undecidable in general, so it cannot be implemented by a program compiler. Class or object hierarchies must be carefully designed, considering possible incorrect uses that cannot be detected syntactically. This issue is known as the Liskov substitution principle. Along with exploring the capabilities and pitfalls of object-oriented programming, it describes 23 common programming problems and patterns for solving them. As of April , the book was in its 36th printing.
Both object-oriented programming and relational database management systems RDBMSs are extremely common in software today [update]. Since relational databases don't store objects directly though some RDBMSs have object-oriented features to approximate this , there is a general need to bridge the two worlds.
The problem of bridging object-oriented programming accesses and data patterns with relational databases is known as object-relational impedance mismatch. There are a number of approaches to cope with this problem, but no general solution without downsides. OOP can be used to associate real-world objects and processes with digital counterparts.
However, not everyone agrees that OOP facilitates direct real-world mapping see Criticism section or that real-world mapping is even a worthy goal; Bertrand Meyer argues in Object-Oriented Software Construction  that a program is not a model of the world but a model of some part of the world; "Reality is a cousin twice removed".
At the same time, some principal limitations of OOP have been noted. However, Niklaus Wirth who popularized the adage now known as Wirth's law: OOP was developed to increase the reusability and maintainability of source code. With the increasing relevance of parallel hardware and multithreaded coding , developing transparent control flow becomes more important, something hard to achieve with OOP. Responsibility-driven design defines classes in terms of a contract, that is, a class should be defined around a responsibility and the information that it shares.
This is contrasted by Wirfs-Brock and Wilkerson with data-driven design , where classes are defined around the data-structures that must be held. The authors hold that responsibility-driven design is preferable. Luca Cardelli has claimed that OOP code is "intrinsically less efficient" than procedural code, that OOP can take longer to compile, and that OOP languages have "extremely poor modularity properties with respect to class extension and modification", and tend to be extremely complex.
The problem with object-oriented languages is they've got all this implicit environment that they carry around with them.

You wanted a banana but what you got was a gorilla holding the banana and the entire jungle. A study by Potok et al. OOP languages have no unique strengths, and inflict a heavy burden of unneeded complexity. Alexander Stepanov compares object orientation unfavourably to generic programming: I find OOP technically unsound.
It attempts to decompose the world in terms of interfaces that vary on a single type. I find OOP philosophically unsound. It claims that everything is an object. Paul Graham has suggested that OOP's popularity within large companies is due to "large and frequently changing groups of mediocre programmers". According to Graham, the discipline imposed by OOP prevents any one programmer from "doing too much damage". Leo Brodie has suggested a connection between the standalone nature of objects and a tendency to duplicate code  in violation of the don't repeat yourself principle  of software development.
Steve Yegge noted that, as opposed to functional programming: Object Oriented Programming puts the Nouns first and foremost. Why would you go to such lengths to put one part of speech on a pedestal? Why should one kind of concept take precedence over another?
Färber, Günther [WorldCat Identities]
It's not as if OOP has suddenly made verbs less important in the way we actually think. It's a strangely skewed perspective. Rich Hickey , creator of Clojure , described object systems as overly simplistic models of the real world. He emphasized the inability of OOP to model time properly, which is getting increasingly problematic as software systems become more concurrent. Raymond , a Unix programmer and open-source software advocate, has been critical of claims that present object-oriented programming as the "One True Solution", and has written that object-oriented programming languages tend to encourage thickly layered programs that destroy transparency.
Rob Pike , a programmer involved in the creation of UTF-8 and Go , has called object-oriented programming "the Roman numerals of computing"  and has said that OOP languages frequently shift the focus from data structures and algorithms to types. Objects are the run-time entities in an object-oriented system.
They may represent a person, a place, a bank account, a table of data, or any item that the program has to handle. There have been several attempts at formalizing the concepts used in object-oriented programming. The following concepts and constructs have been used as interpretations of OOP concepts:. For example, some definitions focus on mental activities, and some on program structuring. One of the simpler definitions is that OOP is the act of using "map" data structures or arrays that can contain functions and pointers to other maps, all with some syntactic and scoping sugar on top.
Inheritance can be performed by cloning the maps sometimes called "prototyping". From Wikipedia, the free encyclopedia. For other meanings of object-oriented, see Object-orientation. For a list of object-oriented programming languages, see List of object-oriented programming languages. Comparison of programming languages object-oriented programming and List of object-oriented programming terms. Object-oriented programming is more than just classes and objects; it's a whole programming paradigm based around objects data structures that contain data fields and methods.
It is essential to understand this; using classes to organize a bunch of unrelated methods together is not object orientation. UML notation for a class. This Button class has variables for data, and functions. Through inheritance a subclass can be created as subset of the Button class. Objects are instances of a class.
