Graphics class allows us to draw strings on the frame with its method drawString(). Following is the signature. void drawString(String str1, int x, int y): x and y are the coordinates where the string str1 is to be drawn on the frame. Following program illustrates. import java.awt.*; public class StringsDrawing extends Frame { public StringsDrawing() …
Java Graphics Draw Lines Summary: By the end of this tutorial "Java Graphics Draw Lines", you will come to know the drawing of lines on frame. Drawing graphics is very simple in Java. The line drawing takes four parameters of starting point x and y coordinates and ending point x and y coordinates. Supporting method …
This code gives strength on AWT graphics programming. There are no predefined methods that can be used straightaway to place the text in the center of the frame and also underline the text. Some programming techniques are required to solve the task. Example on Java Centered Text with Underline The following program places the sting …
There are no predefined methods to draw a cylinder, cube and circle. Using existing methods of Graphics class like drawOval(), drawRect(), drawArc() etc., the task can be done. import java.awt.*; import java.awt.event.*; public class SpecialFigures extends Frame { public SpecialFigures() { setTitle(“Special Effects”); setSize(450,550); setVisible(true); } public void paint(Graphics g) { // to draw a …

Java Retrieve Color Information Summary: Apart using colors in graphics, you can retrieve the information of the components of Color object. Comfortable to read in simple terms in "Java Retrieve Color Information". We have learnt about Color class, how to create Color objects both RGB and HSB models and the predefined colors Java supports. Now …
java.awt.Graphics class comes with many methods of drawing and also with some non-drawing methods that will support drawing indirectly. These methods include clearRect() and copyArea() etc. clearRect() clears a part of graphical area where a drawing may exist with its own background. When cleared, the cleared area shows the background area of the frame (a …
A polygon is a closed figure with many lines joined one to another. The ending point of one line is the starting point to another line and finally the last point is joins with the first point. java.awt.Graphics class comes with two methods and one constructor to draw polygons. void drawPolygon(int x[], int y[], int …
