how to change submit button according to list order Java?

Question

currently i'm in middle of something which is i have a jsp page to get no of beams. In the next page i want next, submit button according to this order

if beam = 1 (submit)
if beam = 2 (next, submit)
if beam = 3 (next, next, submit)
if beam = 4 (next, next, next, submit)

This is what i did so far but its not working as expected...

if(patient.getBeamsno()==1 ){
        map.put("submit");

    }
    else{

    map.put("next");
    }
