In object oriented programming, you consider the object which you are programming about, for example, a car. You then consider the attributes about the object, for example, the make, model, color, year built, etc. You also have consider the operations of the object. i.e. What can it do? A car for example could turn on…
Static methods in Java work on the same basic idea of static functions in other languages like C/C++. The idea is that sometimes you have a function that either needs to be shared between instances, instead of tied to a specific instance, or to be used without needing to create an object from the class…
Now, this is not an in depth explanation of References, but is a good introductory/overview of Java References. In C/C++, you had pointers. You’d create an object and point to its location in memory, and it was great when you had limitations and different segments of memory to work with. However, you had to keep…
Importing a package allows me to import a class, or set of classes into my application that I can use. (These will be outside of the package that I create for my own project.) These packages act like libraries in other languages where a lot of work might be done for you already, and you…
Starting in the 2000’s when computers started to get faster, a lot of languages added a new type of loop, that is faster to write for the developer, but often a little slower to run. However, because of the new found computer speed, it wasn’t deemed to be a major issue. That loop was called…
Arrays in Java are similar to C/C++ arrays, however there are some special unique things about them which make Java Arrays a little easier to work with in my opinion. Like in C/C++ you can have single dimensional or multidimensional arrays. Advantages to Arrays Like a C/C++ array, the array in Java is a contiguous…
Loops in Java work similarly to how you remember loops in C/C++ most likely. You have your counting loop (for), as well as your pretest conditional loop (while), and the conditional post test loop (do-while). Each of these work the same way you would expect them to in C/C++. For Loop The for loop is…
Compared to some languages, you might find writing out basic output in Java…well…overly complex. However, once you understand Java, you will see that it is complex, but for a reason. Let’s first consider some languages you might have already seen. Each one of these prints “Hello World” to your console window. So how does Java…
