For a rounded rectangle, you can use fillRoundRect(int x, int y, int width, int height, int arcWidth, int arcHeight). If you instead wanted to fill the rectangle with a given color, then you need to use the fillRect(int x, int y, int width, int height) method, in addition to setColor(). You can also use the setColor() method to set your rectangle’s border color. When you provide archWidth and arcHeight of (0,0), you get a normal rectangle. Take particular note of the second example. Here are a few examples of how to use this method: g.drawRoundRect(100, 100, 40, 120, 35, 35) In that case, you need to use the drawRoundRect(int x, int y, int width, int height, int arcWidth, int arcHeight) method. However, in some instances a programmer might want to create a rectangle with rounded edges.
The above method creates a normal rectangle (i.e rectangle with pointed edges). This method draws a rectangle of a given width value and height value from coordinates (x,y), relative to your container object: g.drawRect(100, 100, 40, 120) // example of rectangle To draw a rectangle in a Java application, you need to use the drawRect(int x, int y, int width, int height) method. Would draw a line with the starting coordinates of x42 and y55 and ending at coordinates x130 and y25 on a grid.
This draws a line from the cartesian coordinates (x1,y1) to (x2,y2). You can create a simple line by using the drawLine(int x1, int y1, int x2, int y2) method. The following sections describe how programmers can draw common geometric shapes using Java. Inside the paint(Graphics g) function, you can then call the class for the particular 2D object. The first step in creating a 2D geometric shape in Java is to provide a Graphics parameter to the paint() function.
In this programming tutorial, developers will learn how to use the Graphics2D class and the Shape interface to render geometric 2D graphics in Java.īefore we begin, however: are you looking to learn how to develop software in Java in an online course? If so, we have a list of the Best Online Courses to Learn Java to help get you started. These geometries can be found in the package. In addition, the Shape interface is used to define objects that represent geometric shapes. This class is part of the java.awt package. Java provides the Graphics2D class for rendering two-dimensional (2D) text, shapes, and images in Java applications.
