What is Java? It is unarguably one of the most globally recognized and widely-used object-oriented (OO) programming languages granting the least possible implementation-related dependencies. It’s famous in the developer’s community due to its WORA concept, meaning Write Once and Run Anywhere ...
What is matplotlib library in Python? Matplotlib isa plotting library for the Python programming language and its numerical mathematics extension NumPy. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK. ......
This is just the identity function, but it calculates the result with the help of an inner function. The way this works is that theInnerfunction receives a hidden parameter that tells it where theOuterprocedure’s local variables are. In practice, what is passed is a pointer to theOuterproc...
This is a common way to resolve complexity. It’s no wonder that the early programming languages like Cobol, Pascal, and C are based on this concept. The solution is implemented as a set of algorithms in which eachalgorithmis represented by a function or a procedure. That is why these la...
Elegantly employing architectural patterns, along with design, deployment, integration, and other specialized patterns, is the way forward for producing and running next-generation software solutions. An arsenal of software patterns (architecture, design, deployment, integration, and so on.) come in ...
Is the Idiom Boilerplate Code That Should Be Simplified? If you’re coming from a different object-oriented programming language, you might think that Python’s name-main idiom is an entry point akin to themain()functions in Java or C, but clumsier: ...
Note:Before Python 3.5, enabling one of the optimization levels with the-Oor-OOflag would compile the bytecode into a separate.pyofile in the cache folder. This changed afterPEP 488went into effect, and the optional optimization level is now encoded in the.pycfile name. ...
you know that Java and programming in general is full of acronyms,0:09 jdk, jre, jvm, jar, oo, ide, dry, di.0:15 POJO, and the list goes on and on, but0:21 there is one acronym I've used in this course that is integral to the development0:26 ...
The University of Limerick, in Ireland, offers a complete COBOL programming course online, courtesy of its Department of Computer Science and Information Systems. It is not as up-to-date as some other resources, but given how little COBOL changes with time, that’s not necessarily a defect. ...
In general, Go tends to borrow and adapt features from other programming languages, while shedding most of the complexity. For example, you can use some object-oriented (OO) programming features and design patterns in Go, but the full OO paradigm isn't fully implemented. You'll learn why ...
