public class testprocedures extends jpanel {     private static jlabel procedurelabel;     private static jbutton orderbutton, resetbutton, quitbutton;     private static jtextarea orderdetails;     private static jcheckbox[] procedure;     private static int num_procedures= 5;     static jtextfield patientidfield;       public testprocedures()     {         super();         patientidfield = new jtextfield("enter patient id number", 25);         add(patientidfield);          setpreferredsize(new dimension(350,300));         setlayout(new gridlayout(1,1));         add(pane, new dimension(1,1));         setvisible(true);          jframe frame = new jframe("procedures");         frame.setcontentpane(split);         frame.pack();         frame.setvisible(true);*/     }      public void selectprocedures()     {         procedurelabel = new jlabel("select procedures");         procedure= new jcheckbox[num_procedures];         procedure[0] = new jcheckbox("extraction",false);         procedure[1] = new jcheckbox("filling",false);         procedure[2] = new jcheckbox("cleaning",false);         procedure[3] = new jcheckbox("crown",false);         procedure[4] = new jcheckbox("x-ray",false);           orderbutton = new jbutton("set procedures");         orderbutton.addactionlistener(new actionlistener()                 {                     public void actionperformed(actionevent event){                            processorder();                     }                 });          resetbutton = new jbutton("reset patient procedures form");         resetbutton.addactionlistener(new actionlistener()                 {                     public void actionperformed(actionevent event){                         resetform();                     } });          quitbutton = new jbutton("quit program");         quitbutton.addactionlistener(new actionlistener()                 {                     public void actionperformed(actionevent event){                          system.exit(0);                     } });          orderdetails = new jtextarea("awaiting procedures....",5,40);         add(procedurelabel);         (int index=0; index < num_procedures;++index)             add(procedure[index]);         add(orderbutton);         add(resetbutton);         add(quitbutton);         add(orderdetails);     }      static void processorder()     {         string order = "procedures selected:";         boolean proceduresselected= false;          string patientid = patientidfield.gettext();         int patientnumb = integer.parseint(patientid);         arraylist<patient> patientlist = dentisttabbed.getpatientlist();         arraylist <procedure> proclist = new arraylist<procedure>();         (int index=0; index < num_procedures;++index)             if (procedure[index].isselected())             {                 //here                 for(patient pat: patientlist)                 {                     if(pat.getpatientnumber()==patientnumb)                     {                          //pat.addprocedure(procedure);                         //proclist.add(procedure);                      }                 }                 //here                 proceduresselected = true;                 order += "\n"+ procedure[index].getlabel();             }         if (!proceduresselected)             order += "no procedure selected.";         order += ".";         orderdetails.settext(order);     } } 

a general solution:

checkbox.setselected(true); list.add(checkbox);
