the dots on the image are supposed to be in the exact positiolatituden of the city $,$ i gave my java code a file of some cities and its longitude and latitude and i calculated x and y values from them $,$ this the code public double calculateX$()\{$

$//$ Convert longitude to radians

double radLongitude $=$ Math.toRadians$($longitude$)$;

$//$ Apply Mercator projection formula

return $(($radLongitude $+$ Math.PI$)*($MAP$\_$WIDTH $/(2*$ Math.PI$)))$;

$\}$

$//$ Method to calculate y coordinate based on latitude using Mercator projection

public double calculateY$()\{$

$//$ Convert latitude to radians

double radLatitude $=$ Math.toRadians$($longitude$)$;

$//$ Apply Mercator projection formula

double mercatorY $=$ Math.log$($Math$.$tan$(($Math$.$PI $/4)+($radLatitude $/2)))$;

$//$ Scale and translate y coordinate to fit within map dimensions

return $(($MAP$\_$HEIGHT $/2)-($MAP$\_$WIDTH $*$ mercatorY $/(2*$ Math.PI$)))$;

$\}$ fix it please
