Java获取最大值和最小值

// 获取最大ID值
		int maxId = 0;
		for (Project project : projectList) {
			int projectId = Integer.parseInt(project.getId());
			maxId = projectId > maxId ? projectId : maxId;
		}

// 获取最小ID值
		int minId = 0;
		for (Project project : projectList) {
			int projectId = Integer.parseInt(project.getId());
			minId = projectId < minId ? projectId : minId ;
		}
