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();

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.
