Compulsory / Elective: Compulsory
1. Experimental content
1) Simple preparation calculator, complete arithmetic modulo operation.
(2) requires two numbers input from the keyboard, using the decision statement to select an operation after the calculation result output, then it is determined to continue to select and calculate the loop or exit.
(3) write test code, test verification. ( Https://www.cnblogs.com/rocedu/p/4472842.html )

Run the code
3. Experimental problems encountered in the process and settlement process
- Question 1: has reached the end of the file when parsing
- Problem 1 Solution: Code semicolon or less hit brackets
- Question 2: Missing return statement
- Problem 2 Solution: a calculator code is not written return
- Question 3: may not have been initialized variable
Question 3 Solution: initialization value
Other (perception, thinking, etc.)
This is the first time I began to learn java to write more complex code, from which I learned a lot:
- Less likely to hit some places, such as semicolons, braces
- Reservations are not familiar with the word
Java and C language has many similarities, sometimes common.
