如何将翻新回调实例更改为Lambda表达式?

call.enqueue(new Callback<User>() {  
    @Override
    public void onResponse(Call<User> call, Response<User> response) {
        // todo deal with returned data (user)
    }
    @Override
    public void onFailure(Call<User> call, Throwable t) {
        // todo deal with the failed network request
    }
});

我试过以下方法:

call.enqueue(
    (Call<User> call, Response<User> response) -> {
    // todo deal with returned data (user)
    },
    (Call<User> call, Throwable t) -> {
    // todo deal with the failed network request
});

在接口中找到多个非重写抽象方法 改造2.回拨

用lambda表达式来表示这一点的正确方法是什么?将代码转换为lambda表达式的正确过程是什么?
