Detailed explanation of the basic process of JAVA project development in JAVA development

Practice is the only criterion for testing truth. No matter which programming language you learn, the final destination is a project or project, and JAVA is no exception. When learning JAVA, whether it is a university major, self-study or training, at the end of the study, you need to take a project to test your learning. Therefore, let’s briefly talk about the basic process of JAVA project development here.

1. Project Startup

A good start is half the battle. When getting a project, there are many issues that need to be considered. It is impossible to analyze them one by one in the startup stage. In order to get a good start, during the project startup stage, you only need to briefly discuss and determine the expected goals and project duration of the project. Establish a project team and establish a good communication mechanism. The number and identities of project team members are determined based on the size of the project, and one person is allowed to hold multiple positions.

2. Business Analysis--Requirements Analysis

What level a project can ultimately achieve depends on what the project can achieve The function is just like my requirement is to make a calculator. No matter how gorgeous the final product is, it is just a calculator. Therefore, at this stage, try to analyze the functions that need to be implemented in the project as thoroughly as possible, down to the smallest details.

3. Write documents--Requirement documents and change records

Thoroughly analyze the business and make corresponding document records, including analysis Identify the function points, development environment and operating environment, estimate the corresponding workload, and clearly divide the work among the project team members.

If business requirements change, you need to submit a change file and upgrade the requirements document version.

4. System design, writing interface documents and change records

Sharpening the knife and chopping firewood without missing a beat. If the design stage is completed well, it can achieve twice the result with half the effort. The design phase requires drawing a complete flow chart and writing interface documents.

If the design changes, you need to submit the change file and upgrade the interface document version.

5. Program development

Function is implemented through code in accordance with coding standards and annotation standards. Naming, interfaces, etc. involved during development must be strictly implemented in accordance with the documents in the design phase.

Prioritize writing test cases.

If changes occur during the development phase that are inconsistent with the documents during the design phase, you need to submit the change file and upgrade the document version.

6. Testing--Test plan, test plan, test report

Testers (or developers) formulate test plans and write tests Plan, execute tests and write test reports.

After the test is completed, the next step can be implemented according to the project positioning, whether for internal use, online testing or others.
