How to Position Shape based on display size

Processing Coding Questions

Looking at the code I expect it to be on the bottom right.

Example to confirm:

size(displayWidth, displayHeight);
println(displayWidth, displayHeight);
println(displayWidth-displayWidth/6, displayHeight-displayHeight/10);
strokeWeight(10);
point (displayWidth-displayWidth/6, displayHeight-displayHeight/10);

This may be helpful:

void setup() 
  {
  size(500, 500);
  //size(displayWidth, displayHeight);
  //fullscreen();
  }

void draw() 
  {
  background(0);
  strokeWeight(3);
  stroke(255, 255, 0);
  point(mouseX, mouseY);
  println(mouseX, mouseY);
  }

:)
