...
It's perfectly possible to template a class on an integer rather than a type. We can assign the templated value to a variable, or otherwise manipulate it in a way we might with any other integer literal:

How does the static modifier affect this code?
...uctor, hence the value of num1 and num2 becomes 1.
And then, again, static int num2=0; will be executed, which makes num2 = 0;.

private A(){
num1++;
num2++;
System.out.println(obj.toString());
}
This will throw a NullPointerException as ob...
