1.8. Why does Java not provide Multiple Inheritance? Having more than one parent class is known as multiple inheritance. Java won’t provide support for multiple inheritances as there may be a chance of raising ambiguity problems. In the case of multiple inheritances, if two parent classes def...
Instructions: In this assignment, you will demonstrate your understanding of core Object-Oriented Programming (OOP) concepts, including objects, classes, methods, loops, and various data types, as well as more advanced concepts such as inheritance and polymorphism. Additionally, you will practice creat...
that chapter, it is for example explained how you share interface by inheritance, how you instantiate an array of child objects that is used to output different messages dependent on which child object that is instanciated. This is a good example of polymorphism (flexible sharing) in practice....
So the conclusion would be that the two design patterns exist to resolve two type of business problems, so even though they look similar, they are not. I hope that this shed some light to resolve the puzzle. If you still don’t understand it, then this time it is not you, it has ...
The risk of deployments is reduced because you practice the process of deployments. By bringing the pain forward, you'll identify problems in your process and tool chains earlier and will be able to optimize accordingly. As a result, the deployment itself will also only change in smaller ...

In practice this means that an object of a child class is also an object of the parent class. In some cases a child class can redefine a method of parent class of the same name, this is calledoverriding. In this situation whenever this method is called the actual method executed is the...
6. Do you have support for multiple inheritance? Multiple inheritance is a great theory that in practice creates as many problems as it solves. "I want to have all the attributes of A and of B combined in C," sounds really good, until you start considering how to handle namecollisions,...
Sometimes, some problems are better suited to using the traditional forms of synchronisation. Go allows us to make use of these Synchonisation Primitives by using the Sync package. + Mutexes A Race Condition happens when two or more threads can access shared data and try to change that shared...
However, in an object-oriented world, utility classes are considered a very bad (some even may say “terrible”) practice. There have been many discussions of this subject; to name a few:Are Helper Classes Evil?by Nick Malik,Why helper, singletons and utility classes are mostly badby Simon...
