将Set集合转成List,并有序排列

问题：项目中获得的部门属性employeeSet是set类型,想要把他转成list类型, 并有序输出出来

 

			/* 获取set集合 */
			Set<Employee> employeeSet = department.getEmployeeSet();
			/* 将Set集合转为List,这样获得的list并不能有序排列*/
			List<Employee> employeeList = new ArrayList<Employee>(employeeSet);
			
			/*将list有序排列*/
			Collections.sort(employeeList, new Comparator<Employee>() {
				public int compare(Employee arg0, Employee arg1) {
					return arg0.getEmployeeId().compareTo(arg1.getEmployeeId()); // 按照id排列
				}
			});
