How to concert String to int?

How to concert String to int? I've tried to use parseInt() and valueOf(), but it can not work.

thank you!

Hi Kevin,

may be you used parseInt () in a wrong way.
Try this (I am sure this works, I use this code - if not, contact me again!!!):

Integer aInt = null;
int tmp = aInt.parseInt(aString);




Another possibility (I use this as well) is following:

String wrapperString = "2";
Integer wrapperInt;
int wrapperIntResult;
wrapperInt = Integer.valueOf(wrapperString);
wrapperIntResult = wrapperInt.intValue();





Andi

Try

String str = "12345";
Integer ii = new Integer(str);
int i = ii.intValue();

Integer.parseInt("1243");//returns an int
Float.parseFloat("12.23");//returns a float
Byte.parseByte("12");//returns a byte
Long.parseLong("12543241");//returns a long
Double.parseDouble("12355.3");//returns a double
All of the "wrapper" classes have the equivalent method except for Character.
