检查是否从JPS文件中选中了一个复选框

Question

boolean flag_outlook ;
            String stringoutlook = request.getParameter("Send_outlook");
            if (stringoutlook != null)
                flag_outlook = true;
            else
                flag_outlook = false;



            String dataStartAppoiment = connect.timeFormatForDatabase(dayformat,Integer.parseInt( timefromedit));
            String dataEndAppoiment = connect.timeFormatForDatabase(dayformat, Integer.parseInt(timefromedit)+1);


            if(flag_outlook=true)
            {
                Apppoiment send = new Apppoiment();
                send.Appoiment(dataStartAppoiment, dataEndAppoiment,ContentCell);
            }

Checkbox from JSP look like this

<input type="checkbox"  name="Send_outlook" >

I try to execut a piece of code, if a checkbox is checked (up is my code) but is not working properly, every time my flag is true. I can't understand where is my mistake

Answer 1

The reason your flag is always true is because in your if-statement you say:

if(flag_outlook = true)

That should be:

if(flag outlook == true)

Your problem is you're assigning in stead of comparing.
