Java Third Experiment Agile Development and XP experiment

Experiment three-1

1. Experimental Requirements:
Experimental three agile Development and XP practice http://www.cnblogs.com/rocedu/p/4795776.html, Eclipse content replaced by idea

Refer to Http://www.cnblogs.com/rocedu/p/6371315.html#SECCODESTANDARD To install the Alibaba plug-in to resolve the specification in the code.

Use the tool (Code->reformate code) in idea to reformat the code below, and then look at the Code menu to find a feature that feels best for you. Submit, add your own study number watermark

2. Experimental steps

• First through settings->plugins, Browse repositories ..., download Alibaba Java code Guidelines, Code->reformat Code re-formats the codes, right-click on the project name, and select Encoding protocol scan on the pop-up menu.

Experiment three-2

1. Experiment requirements: In the code cloud to add their own learning partner to their project, confirm the partner's project to join himself, download the complex code of the partner experiment two, add not less than three JUnit unit test cases, after the successful test git Add. Git commit-m "Learn to add content"; git push;

Submit a partner project git log, containing the above git commit information, and add your own watermark information.

Experiment three-4

Experimental requirements: Refer to http://www.cnblogs.com/rocedu/p/6683948.html, in pairs to complete the Java cryptography related content learning, combined with refactoring, git, code standards.

Submit the learning Result Code cloud link and the representative result, must have the student number watermark.

Experimental ideas:

• First, the total number of letters in the plaintext is calculated as long as the M.length () generated during the encryption process is recorded (K1.length equals 300).
• About the frequency of the occurrence of each letter, I added a 26 English alphabet array (feel unnecessary, but did not think of a better method), with two for loop, the clear text of each letter and 26 letters compared, if the same is recorded, the number of each record down and m.length () divide, Because M.length () and the number of records e are int, I then divide it into a double type.
• The coincident exponent, starting with the first letter of the plaintext, is compared with each subsequent letter, the same is recorded, then begins with the second letter, and finally divides the total number of records with the number of comparisons (the sum of the total number of letters-1), because the two numbers are int and the processing method is the same as 3.
