7.9.3 Graphics Software – A Window or a Frame in Java

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.)

Graphics Software– Command: drawLine (1,1,4,4); Sets Four Pixels in the Frame Buffer

Graphic Software– Using Command drawOval (int x, int y, int width, int height). This Draws an Oval Within a Rectangle

Graphics Software – No Entry Sign - Set Color Command From the Color Class

Graphics Software – Using Commands, drawOval, drawLine, and Set Color, We Can Change The Stop Sign

Graphics Software – Using Commands of drawString and drawLine Will Produce This Image.

Graphics Software – drawRoundRectangle (int x, int y, int width, int height, int arcWidth, int arcHeight).

Graphics Software – A Filled Shape Rather Than An Outline

Graphics Software – Using the Command of fillOval (80, 80, 300, 200) Note The Circle Is Outside The Window – This Is Called Clipping

Practice Problems – Write The Sequence of Commands to Draw The House On This Screen

Exercises – Given the Declaration int [ ] [ ] table = new int [5] [3]: How Would You Refer To This Marked Cell

Exercises – Using the drawLine Command Draw An Isosceles Triangle

Exercises – Create three labeled Rectangular Buttons

Exercises – Create the image of a “Teeter-Totter”
