Answer:
B. f2.i is 1 f2.s is 2
Explanation:
In Java there are two type of variables, first is static variables and second is instance variable. static variable class variable which means you can have only one variable for all instance of that class. But instance variable will only for instance/object of that class.
For this code example, i is and instance variable, for every instance of class Foo, there will be separate i variable. but s is a static variable and that will be associated with class.
So in this program the first instance incremented the s variable and changed its value to 1 as int's default value is 0 in the constructor. So for second instance, the s value changed to 2 that's why it prints f2.s as 2 and as we know i is instance variable and every instance of foo class have there own copy of i variable so it's value will remain same for every instance.
Human centered technology often recommends best practices to computer designers and manufacturers, ...............
Human-Computer Interaction is a study that particularly focuses more on the design of computer technology and the interaction between humans and computers. Since the 1980s when HCI surfaced, it has become a crucial tool in popularizing the idea that the interaction between a user and a computer should resemble a human-to-human, open-ended dialogue.
