7.9.3 Graphics Software – A Window or a Frame in Java
22
A DrawLine (int x1, int y1, int x 2, int y 2). This Draws A Straight Line From Point (x1, y1) On The Screen To Point (x2, y2.)
23
Graphics Software– Command: drawLine (1,1,4,4); Sets Four Pixels in the Frame Buffer
24
Graphic Software– Using Command drawOval (int x, int y, int width, int height). This Draws an Oval Within a Rectangle
25
Graphics Software – No Entry Sign - Set Color Command From the Color Class
26
Graphics Software – Using Commands, drawOval, drawLine, and Set Color, We Can Change The Stop Sign
27
Graphics Software – Using Commands of drawString and drawLine Will Produce This Image.
28
Graphics Software – drawRoundRectangle (int x, int y, int width, int height, int arcWidth, int arcHeight).
29
Graphics Software – A Filled Shape Rather Than An Outline
30
Graphics Software – Using the Command of fillOval (80, 80, 300, 200) Note The Circle Is Outside The Window – This Is Called Clipping
31
Practice Problems – Write The Sequence of Commands to Draw The House On This Screen
32
Exercises – Given the Declaration int [ ] [ ] table = new int [5] [3]: How Would You Refer To This Marked Cell
33
Exercises – Using the drawLine Command Draw An Isosceles Triangle
34
