How to store int and string value in bean class?

Tani :

I know this is very basic question yet I am unable to get the perfect answer. I have one bean named Order in which there is one object product_size such as

public Class Order{
      private String product_size;
} 

Setter and Getter methods are defined respectively in that class. The problem is that product_size may contain string variable such as S or Integer value such as 7.

I am unable to store the Integer value in that bean object.

Tani :

I have done with only one bean instance and I am check that if value is string it should be added in bean object Simply else Integer.toString() method will convert the int value to String.

Example is given below-

String str;      // it is dynamic let there are two values in this 'S' and 8
if (str instancof String){
   order.setProduct_Size(str);
}else{
  order.setProduct_Size(Integer.toString(str));
}
