To make the code more readable, let’s use Rectangle objects to represent bounding boxes. Once you have installed BlueJ, you need to customise your BlueJ environment for ECS courses. We can use the oval we just drew as the face, and then add two ears. This should put BlueJ in your Start menu. Suppose we want to draw a “Hidden Mickey”, which is an icon that represents Mickey Mouse (see ). You can set the background color of the Canvas by invoking setBackground: tBackground(Color.white) You can create your own colors by specifying the red, green, and blue ( RGB) components.įor example: Color purple = new Color(128, 0, 128) Įach value is an integer in the range 0 (darkest) to 255 (lightest). LightGray magenta orange pink white yellow Other colors include: black blue cyan darkGray gray green The setColor method determines the color of everything that gets drawn afterward.Ĭolor.red is a constant provided by the Color class to use it you have to import . To choose the color of a shape, invoke setColor on the Graphics object: g.setColor(Color.red) Graphical coordinates are measured in pixels each pixel corresponds to a dot on the screen. That way, x and y are always positive integers.įigure B.1 shows these coordinate systems. Alternatively, you can also use Quick Open (Ctrl+P) then enter the command to search the. In contrast, Java uses a coordinate system where the origin is in the upper-left corner. Project view also provide a great overview of your project. You are probably used to Cartesian coordinates, where x and y values can be positive or negative. If you run this code, you should see a black circle on a gray background. The application doesn’t end after the main method returns instead, it waits for the JFrame to close. Once the frame is visible, the paint method is called whenever the canvas needs to be drawn for example, when the window is moved or resized. Pack the frame (resize it) to fit the canvas, and display it on the screen.Create a Drawing object (which is the canvas), set its width and height, and add it to the frame.Create a JFrame object, which is the window that will contain the canvas.You can read about the other methods in the documentation, which you can find by doing a web search for “Java Canvas”. The Drawing class extends Canvas, so it has all the methods provided by Canvas, including setSize. The same steps can be used when you want to import video and music file. Alternatively, you are able to click on the 'Import Media Files Here' button to select the picture from your local to import to the program. JFrame frame = new JFrame( 'My Drawing') Import video, photo or music to the program: In the editing window, you can simply drag and drop the picture to the main interface to import it to the program. Here is an example program that draws a circle using the fillOval method: import The Graphics class provides basic drawing methods such as drawLine, drawRect, and drawString. There are several ways to create graphics in Java the simplest way is to use and .Ī Canvas is a blank rectangular area of the screen onto which the application can draw. We are only going to scratch the surface of graphics programming you can read more about it in the Java tutorials at. Click here to learn about it.The Java library includes a simple package for drawing 2D graphics, called java.awt.ĪWT stands for “Abstract Window Toolkit”. You can also use this image to set the background which I showed in my other post named 'How to set a background image in java'.

Now you can add any number of images and make your projects cool. Here I used ImageIcon class and also setIcon() function of JLabel class. Here you have to select the image which you want to add to the project.Īfter selecting the image you will see that it is being included in the project and also in the JLabel. There you will see an icon property, click the browse button.Ī new window will open, select the 'External Image' option and then click the 'Import to Project' button. Then select the JLabel and go to the properties window.

I have written this article, in which I will show you how to add an image to a project using JLabel.įirstly, create a JFrame form file and add a JLabel to the JFrame. Sometimes we require adding images in the java projects so that they look cool.
