Converting String to Integer

Hello everyone,

I'm having a little bit of trouble converting a string a an integer:



If I set string1 = "5" and string2 = "4" the output is "9". But like I excepted it doesn't work when the strings have spaces in them . How do I remove does spaces in the beginning? Does anyone know a built-in method from the APIs or an alternative way around this problem

Thank-you

[edit - change 'quote' tags to 'code' tags]

Olivier,

I change your post a little. When you want to post code, don't use the 'quote' tags, but the 'code' tags. This will preserve your formatting, making it easier to read.

Go through the Integer class; there are probably several methods and a constructor which take Strings as parameters.
 
It is sorta covered in the JavaRanch Style Guide.
