CodePudding user response:

The s.c lose (); Comment out you performed a was shut down

CodePudding user response:

Your code Scanner shut down, so called after complains, will be s.c lose (); Comment out;
Did you call in the class B class A member variable a1 and b1, because before you use this variable does not have the assignment, so the two values in A class B is the default value is 0, pay attention to the member variable and the scope of local variables,

CodePudding user response:

reference source on the second floor is a ghost reply:

close the Scanner in your code, so called after complains, will be s.c lose (); Comment out;

Speak very detailed
