The Java language has always been a very popular programming language. It can run across platforms and has good scalability and maintainability. In Java development, Git has become one of the most popular version control tools. In collaborative development, Git provides important tools that can facilitate the team's code management and improve development efficiency and code quality. This article will introduce Git collaborative development in Java language, including basic operations of Git, branch management, merging, team collaboration, etc.

1. Basic operations of Git

Git is a distributed version control system. The main difference between it and other version control systems is that Git does not rely on a central server. Each developer Versions can be managed and modified locally. When using Git for collaborative development, you first need to understand some basic operations, as follows:

1. Clone code library

Developers can use Git's cloning operation to clone projects remotely Clone the library to your local computer for development and modification. This can be achieved using the Git clone command, for example:

git clone git@github.com:username/repository.git

2. Add files

In During development, when you need to add newly created or modified files to Git version management, you need to add them first. You can use the following command to add files to the local repository:

git add somefile.java

3. Submit to the local repository

After adding the file, you need Perform a commit operation. The commit operation saves the modified content to the local code base and adds a description. You can use the following command:

git commit -m "commit message"

4. Push to the remote library

When the code of the local library is modified and submitted Afterwards, developers can push the modified content to the remote library to keep the code synchronized. Use the following command to push:

git push

2. Branch management

Branch is one of the very important and flexible concepts of Git. Branch can divide the code base into The workflow is separated into multiple independent development lines, so that each developer can develop on his own branch without affecting the main code. For example:

1. Create a branch

During development, you can create a new branch through the following command:

git branch new-branch

2. Switch branch

Use the following command to switch to the specified branch:

git checkout new-branch

3. Delete branch

Branches that are no longer needed can be deleted using the following command:

git branch -d new-branch

3. Merge

Merge is a collaborative development process in Git A very important step, it merges code changes on different branches together. The following are some basic operations of merging:

1. Merge branches

Assuming that you need to merge the dev branch into the master branch, you can use the following commands in sequence:

git checkout master
git merge dev

2. Resolve conflicts

When merging branches, conflicts may occur, and you need to manually resolve the conflicts. After resolving the conflict, you need to perform the commit operation again:

git add conflict-file.java
git commit -m "resolve conflict"

4. Team collaboration

When multiple people collaborate on development, it is necessary to reasonably allocate work and manage the work progress and code modifications of team members. Here are some methods for Git team collaboration:

1. Code Review

Code review is an essential part of team collaboration. Co-developers review and modify the code to ensure the quality of the modified code. You can use the following command to review the code:

git diff

2. Submit changes

After the developer completes the modification and review of the code, it can be submitted change. Generally, before making a merge request, developers should push the code to a shared remote library and then initiate a merge request.

git push origin your-branch

The above is an introduction to Git collaborative development in Java language. By introducing the basic operations of Git, branch management, merging, and team collaboration, it can help developers better use Git for collaborative development. In practical applications, it is also necessary to optimize and adjust according to your actual situation to achieve better results.
