AWT Rectangle2D Class
Introduction
The Rectangle2D class states a rectangle defined by a location (x,y) and dimension (w x h).
Class declaration
Following is the declaration for java.awt.geom.Rectangle2D class:
public abstract class Rectangle2D extends RectangularShape
Field
Following are the fields for java.awt.geom.Arc2D class:
static int OUT_BOTTOM -- The bitmask that indicates that a point lies below this Rectangle2D.
static int OUT_LEFT -- The bitmask that indicates that a point lies to the left of this Rectangle2D.
static int OUT_RIGHT -- The bitmask that indicates that a point lies to the right of this Rectangle2D.
static int OUT_TOP -- The bitmask that indicates that a point lies above this Rectangle2D.
Class constructors
S.N. | Constructor & Description |
---|---|
1 | protected Rectangle2D() This is an abstract class that cannot be instantiated directly. |
Class methods
S.N. | Method & Description |
---|---|
1 | void add(double newx, double newy) Adds a point, specified by the double precision arguments newx and newy, to this Rectangle2D. |
2 | void add(Point2D pt) Adds the Point2D object pt to this Rectangle2D. |
3 | void add(Rectangle2D r) Adds a Rectangle2D object to this Rectangle2D. |
4 | boolean contains(double x, double y) Tests if the specified coordinates are inside the boundary of the Shape. |
5 | boolean contains(double x, double y, double w, double h) Tests if the interior of the Shape entirely contains the specified rectangular area. |
6 | abstract Rectangle2D createIntersection(Rectangle2D r) Returns a new Rectangle2D object representing the intersection of this Rectangle2D with the specified Rectangle2D. |
7 | abstract Rectangle2D createUnion(Rectangle2D r) Returns a new Rectangle2D object representing the union of this Rectangle2D with the specified Rectangle2D. |
8 | boolean equals(Object obj) Determines whether or not the specified Object is equal to this Rectangle2D. |
9 | Rectangle2D getBounds2D() Returns a high precision and more accurate bounding box of the Shape than the getBounds method. |
10 | PathIterator getPathIterator(AffineTransform at) Returns an iteration object that defines the boundary of this Rectangle2D. |
11 | PathIterator getPathIterator(AffineTransform at, double flatness) Returns an iteration object that defines the boundary of the flattened Rectangle2D. |
12 | int hashCode() Returns the hashcode for this Rectangle2D. |
13 | static void intersect(Rectangle2D src1, Rectangle2D src2, Rectangle2D dest) Intersects the pair of specified source Rectangle2D objects and puts the result into the specified destination Rectangle2D object. |
14 | boolean intersects(double x, double y, double w, double h) Tests if the interior of the Shape intersects the interior of a specified rectangular area. |
15 | boolean intersectsLine(double x1, double y1, double x2, double y2) Tests if the specified line segment intersects the interior of this Rectangle2D. |
16 | boolean intersectsLine(Line2D l) Tests if the specified line segment intersects the interior of this Rectangle2D. |
17 | abstract int outcode(double x, double y) Determines where the specified coordinates lie with respect to this Rectangle2D. |
18 | int outcode(Point2D p) Determines where the specified Point2D lies with respect to this Rectangle2D. |
19 | void setFrame(double x, double y, double w, double h) Sets the location and size of the outer bounds of this Rectangle2D to the specified rectangular values. |
20 | abstract void setRect(double x, double y, double w, double h) Sets the location and size of this Rectangle2D to the specified double values. |
21 | void setRect(Rectangle2D r) Sets this Rectangle2D to be the same as the specified Rectangle2D. |
22 | static void union(Rectangle2D src1, Rectangle2D src2, Rectangle2D dest) Unions the pair of source Rectangle2D objects and puts the result into the specified destination Rectangle2D object. |

Rectangle2D 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) { Rectangle2D shape = new Rectangle2D.Float(); shape.setFrame(100, 150, 200,100); Graphics2D g2 = (Graphics2D) g; g2.draw (shape); Font font = new Font("Serif", Font.PLAIN, 24); g2.setFont(font); g.drawString("Welcome to TutorialsPoint", 50, 70); g2.drawString("Rectangle2D.Rectangle", 100, 120); } }
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
