If i pass an integer value as String argument to some function, where i need to add it to integer value. How can i typecast argument from String to integer before adding. The problem i faced is

public int Sum(String str1,String str2){

int sum = str1+str2; //What i need to do here?
return sum;
}

public Static void main(String args[]){


obj.sum("123","456");


}

Welcome to JavaRanch ( ) both of you.

Shaun: This question comes up frequently, at least once every three months, and you obviously know about the problem. It would help kiran nyala if you give a bit more explanation, and also explain why it isn't called "typecast"ing. Also, both of you, consider why that method could beneficially be declared static.
 
I agree. Here's the link: http://aspose.com/file-tools
