Also, these assessments are used to generate your grade on the tutorial assignments.IMPORTANT: The Oracle Java 8 is no longer available to download publicaly. They are a great way to check and make sure you understand what the lesson is about. Whenever you see one, you’ll want to take the time and make sure you are able to complete the assessment successfully before you move on.

Many Codio lessons also include short assessments that help check your code and make sure it is working correctly. Then, we can go back to our file, and choose Java - Run File to execute the code we just compiled. They look a bit different than the command we learned earlier, mainly because these commands include the folder path directly in the command. We should see Codio open a Terminal window, and it will automatically fill in the appropriate command. If we need to compile our program, we can choose Java - Compile File first. Then, we can click on the Run Menu, which is here at the top of the screen, and select the appropriate options there.

Most of the resources in this class will include these options, so feel free to use them anytime.įirst, we’ll need to make sure we have our HelloWorld.java source file open. Hopefully we should see the expected output from our program appear on the Terminal!Ĭodio also includes some shortcuts for compiling and running programs.

You can also refer to the next page for some tips on how to fix common errors in your code.įinally, if everything worked correctly, we can type java HelloWorld to run our program. To fix it, go back to the previous page and see if you can correct the error. If that file isn’t created, or the Java Compiler gives you any output, that probably means that you have a problem in your HelloWorld.java file. That is the Java bytecode for our program. However, we can use the ls command again, and we should now see a new file called HelloWorld.class. If everything works correctly, there won’t be any output. In the Terminal, we can type javac HelloWorld.java to compile our program. So, we’ll use the Java Compiler to perform that action. If so, we can move on.īefore we can run our Java programs, we have to compile the code into a format that the computer can understand. We should hopefully see HelloWorld.java there. Once we are in that folder, we can do ls once again to see the files it contains. So, to enter that folder, we’ll use cd followed by the name of the folder we’d like to open. You can find the folder for the current chapter in the filetree to the far left of the screen. So, we’ll need to open the folder for our current chapter. When we are in the Codio tutorials, we’ll see folders here for each chapter. It is short for “list” and it will give us a list of all of the things inside of our present working directory. To see the files and folders inside that folder, we can use the ls command. That is the default location where all of our code is stored in Codio, so we’ll always start in that folder. In our case, we are in the “home” folder, then inside the “codio” folder, and finally the “workspace” folder. That stands for “present working directory”, and should give you output similar to this. If you are completely new to Linux, there is another video on this page that gives a great overview of the Linux Terminal and how to use it.įirst, we can always find our current location by using the pwd command. On the Terminal itself, we should review a few basic Linux commands that will help us get around the filesystem.
So, there are lots of ways we can get to the Terminal, so take your pick. In addition, most of the Codio books and projects in this course will have an Open Terminal option available on the Run Menu as well. Finally, we can always click on the Terminal icon at the top of the filetree. Or, we can press SHIFT + ALT + T anytime to open it using a keyboard shortcut.
We can go to the Tools menu and find it there. In Codio, there are several ways to access the Terminal. In fact, we could follow very similar steps to compile and run Java code on just about any computer! There are several ways we can accomplish this task.įirst, we can always use the built-in Linux Terminal to compile and run any programs we create. Let’s review how to compile and run a program written in Java using Codio.
