How to parse string containing negative number by j2me api?

I have a string which has numbers. I have to parse this string and store these numbers in int, float, etc. Accordingly 

String str = "100,2.0,-100,19.99,0";

I can do it by Integer.parseInt() and Float.parseFloat() after splitting. But I can't do it for negative number. It throws exception java.lang.NumberFormatException. After searching web I couldn't find any solution for this problem.

So how can I parse a negative integer from string and store into int using j2me api set?

java string java-me

I had a similar problem today and the problem was that the minus sign in the input string was actually an m-dash character. That was nasty! So that's definitely worth checking.

You can split by the delimiter ',' and check if there is a negative sign so multiply the number by -1 or do it by 

Float parseFloat(str);

It will work properly.
