Design ideas:

1.建立一个frame面板，通过添加复选框来选择是否有乘除法，是否有余数，是否有括号以及是否有负数。

2. Control the calculation range and number of topics by adding a text box.

3. When the OK button is clicked, the current window closes, the data is submitted, and a new frame window is created.

4. Control the calculation problem by random number generation and subtraction (0-3 for subtraction respectively, if there is no multiplication, then 0 or 1 will be generated, thereby excluding the multiplication operation)

5. Control division based on whether to select the remainder. If there is no remainder, the product of the generated two random numbers is used as the dividend, and the second random number as the divisor.

6. If a negative number is selected, the addition and subtraction do not do the processing, or the comparison between the meiosis and the size. If the meiosis is greater than the meiosis, the two are exchanged.

7. By creating a JLabel array to output the title to the window, the title coordinates are accumulated according to the number of questions

8. Fill in the answer by creating a text box

9. Parentheses and tests are not repeated.

10. Thread to control topic change
