AWT BasicStroke Class
Introduction
The BasicStroke class states colors in the default sRGB color space or colors in arbitrary color spaces identified by a ColorSpace.
Class declaration
Following is the declaration for java.awt.BasicStroke class:
public class BasicStroke extends Object implements Stroke
Field
Following are the fields for java.awt.geom.Arc2D class:
static int CAP_BUTT -- Ends unclosed subpaths and dash segments with no added decoration.
static int CAP_ROUND -- Ends unclosed subpaths and dash segments with a round decoration that has a radius equal to half of the width of the pen.
static int CAP_SQUARE -- Ends unclosed subpaths and dash segments with a square projection that extends beyond the end of the segment to a distance equal to half of the line width.
static int JOIN_BEVEL -- Joins path segments by connecting the outer corners of their wide outlines with a straight segment.
static int JOIN_MITER -- Joins path segments by extending their outside edges until they meet.
static int JOIN_ROUND -- Joins path segments by rounding off the corner at a radius of half the line width.
Class constructors
S.N. | Constructor & Description |
---|---|
1 | BasicStroke() Constructs a new BasicStroke with defaults for all attributes. |
2 | BasicStroke(float width) Constructs a solid BasicStroke with the specified line width and with default values for the cap and join styles. |
3 | BasicStroke(float width, int cap, int join) Constructs a solid BasicStroke with the specified attributes. |
4 | BasicStroke(float width, int cap, int join, float miterlimit) Constructs a solid BasicStroke with the specified attributes. |
5 | BasicStroke(float width, int cap, int join, float miterlimit, float[] dash, float dash_phase) Constructs a new BasicStroke with the specified attributes. |
Class methods
S.N. | Method & Description |
---|---|
1 | Shape createStrokedShape(Shape s) Returns a Shape whose interior defines the stroked outline of a specified Shape. |
2 | boolean equals(Object obj) Tests if a specified object is equal to this BasicStroke by first testing if it is a BasicStroke and then comparing its width, join, cap, miter limit, dash, and dash phase attributes with those of this BasicStroke. |
3 | float[] getDashArray() Returns the array representing the lengths of the dash segments. |
4 | float getDashPhase() Returns the current dash phase. |
5 | int getEndCap() Returns the end cap style. |
6 | int getLineJoin() Returns the line join style. |
7 | float getLineWidth() Returns the line width. |
8 | float getMiterLimit() Returns the limit of miter joins. |
9 | int hashCode() Returns the hashcode for this stroke. |

BasicStroke Example
Create the following java program using any editor of your choice in say D:/ > AWT > com > tutorialspoint > gui >
AWTGraphicsDemo.javapackage com.tutorialspoint.gui; import java.awt.*; import java.awt.event.*; import java.awt.geom.*; public class AWTGraphicsDemo extends Frame { public AWTGraphicsDemo(){ super("Java AWT Examples"); prepareGUI(); } public static void main(String[] args){ AWTGraphicsDemo awtGraphicsDemo = new AWTGraphicsDemo(); awtGraphicsDemo.setVisible(true); } private void prepareGUI(){ setSize(400,400); addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent windowEvent){ System.exit(0); } }); } @Override public void paint(Graphics g) { Graphics2D g2 = (Graphics2D)g; g2.setStroke(new BasicStroke(3.0f)); g2.setPaint(Color.blue); Rectangle2D shape = new Rectangle2D.Float(); shape.setFrame(100, 150, 200,100); g2.draw(shape); Rectangle2D shape1 = new Rectangle2D.Float(); shape1.setFrame(110, 160, 180,80); g2.setStroke(new BasicStroke(1.0f)); g2.draw(shape1); Font plainFont = new Font("Serif", Font.PLAIN, 24); g2.setFont(plainFont); g2.setColor(Color.DARK_GRAY); g2.drawString("TutorialsPoint", 130, 200); } }
Compile the program using command prompt. Go to D:/ > AWT and type the following command.
D:\AWT>javac com\tutorialspoint\gui\AwtGraphicsDemo.java
If no error comes that means compilation is successful. Run the program using following command.
D:\AWT>java com.tutorialspoint.gui.AwtGraphicsDemo
Verify the following output
