如何组合2个responseEntity和return？

public List<ResponseEntity> combineResponses(ResponseEntity response1, ResponseEntity response2) {
    List<ResponseEntity> combinedResponses = new ArrayList<>();
    combinedResponses.add(response1);
    combinedResponses.add(response2);
    return combinedResponses;
}

public class CombinedResponse {
    private ResponseEntity response1;
    private ResponseEntity response2;

    // getter and setter methods

    public CombinedResponse(ResponseEntity response1, ResponseEntity response2) {
        this.response1 = response1;
        this.response2 = response2;
    }
}

public CombinedResponse combineResponses(ResponseEntity response1, ResponseEntity response2) {
    return new CombinedResponse(response1, response2);
}
