如何使用Lambda表达式创建满足条件的数组列表

Question

I have to write a method body of class Employee containing 3 objects and return an arraylist of employees whose attendance is greater than 70% using lambda expression.

Java

public List<Employee> findAttendance(List<Employee> emp) {
    List<Employee> l = new ArrayList<Employee>();
    l.forEach(emp -> (if(emp.getAttendance() >= 70)) {
            l.add(emp);
     });
}

Answer 1

List<Employee> empsWithGoodAttendance = l.stream()
                                          .filter(e -> e.getAttendance() >= 70)
                                          .collect(Collectors.toList());
