Consider class Example from the previous exercise. For each object first and second, write down the value of the
fields a and x or indicate that the object does not exist (e.g. using a forward slash “/”), after the execution of each of
the following lines of code.
1 Example first = new Example();
2 Example second = new Example(2, "0");
3 first.b();
4 second.c();
5 second.c();
6 first.g();
