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.
 
It is sorta covered in the JavaRanch Style Guide.
