hello,
thank you for your reply, up to now i have wrote some codes that can allow me to enter points in a plane but im still comfused about how i can write codes to find the maximum distance between two points (the two points have to be in different sides) then that maximum distance has to be the diameter of the circle that must enclose all the points entered.
the above is the program that i wrote so far but i need to include a function...

ohhh thank you for your replies.
let me try to change my problem and be more specific.
i'm a beginner in java, i want to write codes that will allow me to enter points in a plane then by clicking on a button i want to find the minimum circle that encloses all the points entered in the plane.
can someone help me please?
thank you
