Total process of program trial count

1. Create a method to run the program

2 The Main method determines whether the number of arrivals to end the trial of the program

3 separate creation method for judging conditions

4. In the judging condition method:

4.1 Create a configuration file that holds the program information, of course, it is empty at this time

4.2 Creating a Property object

4.3 Create a string-type value Reference object and give it a key-worthy method in the Property object

4.4 Add a counter int count = 0; This counter is useful for the first time the program runs, and there is no information for that counter in the configuration file

4.5 To determine whether value is empty, if so, jump directly to the next line of code that is the counter increment; if it is not, we will take the value of the counter in the configuration file and assign it to count in memory, and

To determine if the counter meets the number of times required, and if it satisfies the return true to end the program

4.6 Counter self-increment

4.7 Calling the Set key value method in the Properties object

4.8 Setting a path to the output stream for the profile

4.9 Call the storage method in the properties object to store the counter information.

Counter is difficult ah ... PS: Think of a half-day look
