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…
One approach to dealing with deadlocks is to allow deadlocks to occur and to provide means for detection and recovery. Recovery from a deadlock can be accomplished by destroying one or more of the processes involved in the deadlock, or by removing some of the resources held by the deadlocked processes. The banker’s algorithm emulates…
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…
You will find conditions in Java familiar if you are used to using boolean conditions in C/C++. However, noticed that I said boolean conditions. That is because Java wants boolean conditions, those that generate a true or false answer, instead of the C/C++ conditions which actually look for an integer value. Notice the following below…
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,…
Creating our first file is fairly simple. Using an IDE like Visual Studio Code is a good place to start. Eclipse is another popular IDE, as are some others. However, you only have to have a plain text editor if you want. You can use a command line compiler and run time tool if you…
Java was designed with a couple of main purposes in mind to be Object Oriented from the beginning, as a “write once, run anywhere” model, so that code doesn’t have to be rewritten While the idea behind Java hasn’t always held true, where lots of front end code would be written and run equally on…
