For this homework, you will write a Java class that reads through a text file of drawing commands and draws the appropriate shapes onto JFrames. The following commands must be supported
FRAME width height // sets up a new frame with given width and height (both integers)
COLOR red green blue // sets the current “pen color” to the color with the given rgb components.
RECTANGE x y width height // draws a rectangle with upper left corner at x,y and given width and height (all // given in integers)
CIRCLE x y radius // draws a circle centered at x,y with given radius (as doubles)
ELLIPSE x y xradius yradius // draws an ellipse centered at x,y with semi-radii xradius and yradius (Note:
// these parameters are slightly different than that in Ellipse2D.Double’s
LINE x1 y1 x2 y2 // draws a line from x1,y1 to x2,y2 (as doubles)
A sample command paint_instructions.txt file is as follows:
FRAME 200 100 // open a frame, note: parser must ignore any comments
COLOR 255 0 0 // set color to red
RECTANGLE 20 30 40 20 // draw a red rectangle
COLOR 128 128 128 // set color to gray
CIRCLE 100 50 25 // draw a gray circle
FRAME 100 100 // open a second frame
COLOR 0 0 255 // set color to blue
ELLIPSE 50 50 30 20 // draw a blue ellipse
COLOR 0 255 0 // set color to green
LINE 10 20 90 80 // draw a green line
For simplicity, there should be only one command per line which may end in a comment as shown above.
Your program should read commands and set up appropriate GUI structures in the Java Swing environment. If a command has a syntax error, then your program should detect this and print out a message to the output console indicating the line number from your command file that had the error. Hint: there is an easy way to do this by catching runtime exceptions that are thrown in a try block.
