Question

This code have something wrong, having error in return type.

    public static []double convertLatLong(String lat, String lng) {
        ........
     double latitude=....;
     double longitude=....;

     return (new []double{latitude,longitude});
     }

But it works fine with…

public static double[] convertLatLong(String lat, String lng) {
        ........
     double latitude=....;
     double longitude=....;

     return (new double[]{latitude,longitude});
     }

So, what is difference between them?
While java supports declarations data_type [] var_name as well as data_type var_name [].

Answer 1

You asked: “So, what is difference between them? While java supports declarations data_type [] var_name as well as data_type var_name [].”

Compare carefully:

public static []double convertLatLong(String lat, String lng) // error

is to

public static double[] convertLatLong(String lat, String lng) // correct

AS

[]data_type var_name // error

is to

data_type[] var_name // correct

while

data_type var_name[] // also valid

has nothing in common with either of the function declarations (egads @ Jon)

Does that help?
