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…

Inside of a method, like our main method, we might want to create some variables for use. Java gives us numerous primitive data types that we can use, and within a method, we declare and use them, just like we would in C/C++. Comments You might have noticed the comment above. Comments in Java are…

Just like in C++, each executable Java project should have a main method. This isn’t just the “main” method that is run, but an actual method called main(). If you look at the previous page for creating a file, we can start from there. This will be a little different from the C++ main method,…
