Filter

List<Employee> adminEmployees = employees.stream()                .filter(employee -> employee.getDepartment().equals("ADMIN"))                .collect(Collectors.toList());

All Match

boolean areAllActive = employees.stream()                .filter(employee -> employee.getDepartment().equals("ADMIN"))                .allMatch(Employee::isActive);

Any Match

boolean hasAnyActiveEmployee = employees.stream()                .anyMatch(Employee::isActive);

boolean hasNoneActiveEmployee = employees.stream()                .noneMatch(Employee::isActive);
