Unless there's more code, it doesn't look the value of like str_int gets saved, the input gets assigned to Integer(10) and then thrown away since you can't reassign an input object's reference value.

Mahup, u can make str_int as instance variable of class Data after calling getData() can access the changed value of str_int!

Better way is to add a getter function to the data class that returns the variable value you want (e.g., getStrInt()).
I agree. Here's the link:
