How can i return the value from retrofit onResponse? : I'm beginner in android and write simple retrofit example:<br/>

    LOGININTERFACE mAPISERVICE;
    mAPISERVICE= LOGINGENERATOR.getAPIServices();
    mAPISERVICE.savePost("0016642902","0016642902","password").enqueue(new Callback<LGOINMODEL>() {
        @Override
        public void onResponse(Call<LGOINMODEL> call, Response<LGOINMODEL> response) {
            LGOINMODEL output=response.body();
                            if(response.isSuccessful())
                test[0] ="behzad behzad behzad";
        }

        @Override
        public void onFailure(Call<LGOINMODEL> call, Throwable t) {

        }
    });
<br/>
but in this line:<br/>

     test[0] ="behzad behzad behzad";
<br/>
