To see this, let's create one more Object, this time a Student: Notice how an object now shows up on the object bench.Īll you needed when creating that object was its name, but sometimes Objects ask for more information so they can start off with certain data. You'll get a box asking you to name your new object, but you can leave the default suggestion and click OK.Click on the second menu item, new Staff().To create an actual object, right-click on a Class and click on a "new" menu item. Creating ObjectsĪs mentioned before, Classes are like blueprints to define specific instances (or Objects) of code. The main pane shows a diagram of each Class in a project and their relationships with each other. You should then see the following screen (without the blue markup):īlueJ lets you create and view Classes and Objects in a visual manner. (You can also open a project from within BlueJ by clicking on Project > Open Project. Open the people folder and click on the BlueJ package.If you cannot find it, download a copy of examples and unzip it. On Windows, look in C:\Program Files (x86)\BlueJ or C:\Program Files\BlueJ. Find the folder where BlueJ is installed and open the examples folder inside.You can skip the "real code" parts for now, and come back to them to reference later. We will see different actions that you can do with BlueJ and also how its done with real code.

More About BlueJīlueJ lets you interact with Objects in your code directly which helps when learning concepts or to try something out quickly. You can view a longer BlueJ tutorial on the BlueJ site. This node will cover the basics of using BlueJ and connect it to using Java.
