Help writing a Java program

(please provide photos it works so I'm not studying a nonworking program)

Write a complete version of the Bresenham Midpoint algorithm to handle ALL slope values.  Include appropriate tests for ‘special case’ conditions.  Instead of “WritePixel” write to the screen the coordinates of the pixel that would be drawn.  Your program must implement the algorithm given in class with modifications to handle the special cases.

Different slope values:

m = 0, m = 1, m = > 1, m = infinity (needs special test case) , m < 0 (swap x and y)

The user should be able to enter coordinates and it should output the coordinates it takes to draw from the first point to the last point

Bresenham's Midpoint All Integer Line Scan Algorithm
WritePixel(x0,y0)
x=x0; y=y0
dx=x1-x0; dy=y1-y0
d=2dy - dx
incrE=2dy
incNE=2(dy-dx)
no
_d<=0
yes
d=d+incrNE d=d+incrE
y=y+1
no
X=X+1
WritePixel(x,y)
-X=X1
+
