Question

I am trying to convert a string to Integer/Float/Double but I got a NumberFormatException.

My String is 37,78584, Now I am converting this to any of them I got NumberFormatException.

How can I convert this string to any of them.

Please help me to get out of this problem.

Answer 1

You have to use the appropriate locale for the number like

String s = "37,78584";
Number number = NumberFormat.getNumberInstance(Locale.FRENCH).parse(s);
double d= number.doubleValue();
System.out.println(d);

prints

37.78584

Answer 2

Replace , by "" blank in string and then convert your numbers

String str = "37,78584";
str = str.replaceAll("\\,","");
