java中distinct的用法

<code class="java">Stream<T> distinct()</code>

<code class="java">List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 1, 3, 5);

// 使用 distinct() 去除重复元素
List<Integer> distinctNumbers = numbers.stream()
                                    .distinct()
                                    .toList();

System.out.println(distinctNumbers); // 输出：[1, 2, 3, 4, 5]</code>

<code class="java">Comparator<Employee> employeeComparator = Comparator.comparing(Employee::getId);

List<Employee> employees = ...;

List<Employee> distinctEmployees = employees.stream()
                                         .distinct(employeeComparator)
                                         .toList();</code>

<code class="java">List<String> names = ...;

List<String> distinctNames = names.stream()
                                 .filter(name -> name.length() > 5)
                                 .distinct()
                                 .toList();</code>
