The second week of school classroom tests cum simple Java code is out of question
Code can have the functions of double-digit arithmetic, while ensuring the result of the multiplication does not exceed 100, an integer result of the division, the result of the subtraction is positive.
In addition, the user can also set a number of questions, and the number of rows in each subject.
