对于这个问题，可以将该项目的待办事项拆分成多个backlogs，每个backlog与项目的一个团队相关联。可以使用以下代码示例：

public class Project { private List backlogs; public Project() { backlogs = new ArrayList<>(); } public void addBacklog(Backlog backlog) { backlogs.add(backlog); } }

public class Backlog { private List tasks; private Team team; public Backlog(Team team) { this.team = team; tasks = new ArrayList<>(); } public void addTask(Task task) { tasks.add(task); } }

public class Team { private String name; public Team(String name) { this.name = name; } }

public class Task { private String name; public Task(String name) { this.name = name; } }

// 创建项目 Project project = new Project();

// 创建团队 Team team1 = new Team("Team 1"); Team team2 = new Team("Team 2");

// 创建backlogs并将它们与团队相关联 Backlog backlog1 = new Backlog(team1); Backlog backlog2 = new Backlog(team2);

// 向backlogs中添加任务 backlog1.addTask(new Task("Task 1 for Team 1")); backlog1.addTask(new Task("Task 2 for Team 1")); backlog2.addTask(new Task("Task 1 for Team 2")); backlog2.addTask(new Task("Task 2 for Team 2"));

// 将backlogs添加到项目中 project.addBacklog(backlog1); project.addBacklog(backlog2);
