HOW TO MAKE A BLUEJ PROGRAM EXECUTABLE CODE
We must now 'compile' our source code into bytecode. Now that we are done writing our code, let's close the the editor. 1 day ago &0183 &32 I started working for a company that has some java swing applications and I just discovered how they make java programs into executable jar files (Export > Executable jar file) and that obviously opens the program, but they have some other files labelled with Type: Application instead of 'Executable Jar File', and it has the company logo on it.Add the following line of code inside the Constructor of HelloWorld. Now, let's add the code that will print out Hello World when we run the program. Just ask anyone in the AP class! Here's what my version of BlueJ has as the default code of each class. Now, if you've never programmed before, you may see a lot of daunting looking stuff! Eventually though, what you are looking at below will seem quite familiar and not daunting at all. To do so, right click on the "HelloWorld" icon and select 'Open Editor' Now let's actually start programming!."Helloworld" is just as valid of a classname but " Hello World" is NOT a valid clas name. You cannot have a blank space in the name of a class. By convention class names start iwth a capital letter though Java does not require this. Not surprisingly, the way that you create a new class is to click on the "new class" button!.The blank document with the turned corner represents the project: From this window type in the name of the new project in the text field File name. Click on the Project menu and select New Project. Your screen should now look like this picture. When BlueJ is up and running you should see a window that looks something like this: To create a new program you first need to create a new project. 1) After opening up BlueJ, select 'new project.' Let's call our first BlueJ project " FirstProject".
