Java FX Code Optimization

I'm sure there is some optimization available here - what I am doing is reading the String array emps and creating a RadioButton with the text of the radio button being the value of emps. And I want to every 35 names create a new VBox and write the array there. Can someone skilled in Java give me some pointers on this? for (int i = 0; i < [login to view URL]; i++) { if (x == 0) { [login to view URL]().add(vbxOne); [login to view URL](new Insets(15, 25, 15, 12)); [login to view URL](10); } if (x == 35) { [login to view URL]().add(vbxTwo); [login to view URL](10); [login to view URL](new Insets(15, 25, 15, 12)); } if (x == 69) { [login to view URL]().add(vbxThree); [login to view URL](10); [login to view URL](new Insets(15, 25, 15, 12)); } if (x == 104) { [login to view URL]().add(vbxFour); } if (x <= 34) { RadioButton rb = new RadioButton(); [login to view URL](emps[i]); [login to view URL]().add(rb); } if (x >= 35 && x <= 69) { RadioButton rb = new RadioButton(); [login to view URL](emps[i]); [login to view URL]().add(rb); } if (x >= 70 && x <= 104) { RadioButton rb = new RadioButton(); [login to view URL](emps[i]); [login to view URL]().add(rb); } if (x >= 105) { RadioButton rb = new RadioButton(); [login to view URL](emps[i]); [login to view URL]().add(rb); } x++; }
