java - spreading out objects on a line evenly -

i creating objects on line in window created piece of code:

void createturtles() {      int nrturtles = keyboard.nextint("set amount of turtles: ");      w = new graphicswindow(500, 300);      drawlinez();      (int k = 1; k <= nrturtles; k++) {         turtle t = new turtle(w, 50, 50 + k*10);         t.right(90);         t.setspeed(100);         t.pendown();         turtles.add(t);      } } 

this codeline:

        turtle t = new turtle(w, 50, 50 + k*10); 

creates 1 turtle @ time. right have set turtles have y coordinat of 50, , x coordinat of 50+k*10. because line starts @ x coordinat of 50 , stops @ x coordinat of 250.

now want is, based on nr of turtles created (user inputs this), want turtles spread on line evenly. how it? has line wrote , maybe k value or 10.

the line illustrated in picture (see link below), red line, number of turtles created at.

devide height - 100 of window number of turtles , have distancebetweenturles:

int nrturtles = keyboard.nextint("set amount of turtles: ");  int height = 300; w = new graphicswindow(500, height);  drawlinez();  double distancebetweenturles = (height - 100.0) / nrturtles;  (int k = 1; k <= nrturtles; k++) {     turtle t = new turtle(w, 50, 50 + (int) (k * distancebetweenturtles));     t.right(90);     t.setspeed(100);     t.pendown();     turtles.add(t); }
