Some of my projects require Java version 8. If you started a project using your command line then the error will read "unsupported major.minor version 52".Update to Java 8 here.

First check that you have a compatible version of java, press start and search for "CMD" to open a command window, then type "java -version" and press enter:

You should get an output similar to that below. If you do not have version 1.7 or higher (1.8 for new 2014 projects) or dont have java installed you should get the latest version from here.

All of my java projects are .jar files which should run automatically when you double click on them, if that isn't the case you can try to set this to the default behaviour following this short guide, or you can try to run the program using the steps below:

You need to open the CMD at the location of the program you want to run. For this example I'm going to use FluidApp.jar which is located on my desktop, Desktop is inside my User/TrojanDev directory so all I need to type is "cd Desktop" where 'cd' means open.

I only need to type 'Desktop' because it is in my 'Users\TrojanDev' folder, to open any folder you can start with "C:\", for example:

Once you are in the correct directory type "java -jar application.jar", if the name of the .jar has more than one word in it, you should surround it with brackets:

If the program does not run, an error message should be output into the console, if this happens, googling the error may help.

First check that you have a compatible version of java, Navigate to /Applications/Utilities and double-click on Terminal, then type "java -version" and press enter:

You should get an output similar to that below. If you do not have version 1.7 or higher (1.8 for new 2014 projects) or dont have java installed you should get the latest version from here.

Next, you need to open the CMD at the location of the program you want to run. For this example I'm going to use FluidApp.jar which is located on my desktop, Desktop is inside my User/trojandev directory so all I need to type is "cd ./Desktop" where 'cd' means open and './' means I'm opening a folder that is inside my current location.

I only need to type 'Desktop' because it is in my 'Users\trojandev' folder, to open any folder you can start with just "/", for example:

Once you are in the correct directory type "java -jar application.jar", if the name of the .jar has more than one word in it, you should surround it with brackets:

If the program does not run, an error message should be output into the console, if this happens, googling the error may help.

First you'll need to make sure you have a compatible version of java installed, open up a terminal and type "java -version" and press enter:

You should get an output similar to that below. If you do not have version 1.7 or higher (1.8 for new 2014 projects) or dont have java installed you should get the latest version fromhere.

You may run into problems if you are using an OpenJDK, in which case you'd get the following output:
