Double convert

Question

how to get value after ,
45,7
get number 7
or
45,8
get number 8

Answer 1

s.substring(s.indexOf(',') + 1)

where s is a string containing 45,7 or 45,8 etc.

Answer 2

Rian Pratama Just replace ( , ) with ( . ) in the code snippet above.

s.substring(s.indexOf('.') + 1)

To convert from String to double, you can use

Double.valueOf(s)

For vice versa (double to String)

String.valueOf(d)

where d is a variable of type double.

If you want to remove the dot ( . ), replace it.

s = s.replace(".", "");
