java - Issue with GUI - items won't display -

please excuse incompetence, have gained interest programming. i'll try , concise possible.

basically, have written following code:

main: http://pastebin.com/jtqra3tl support: http://pastebin.com/66gg7sk8

problem: jtextfield labeled "item" won't show up? have done wrong? there need add? appreciated, please not bash "code" hard.

problem:

  frame.setsize(300,100);   frame.setvisible(true);   setlayout(new flowlayout());   item = new jtextfield("lorem ipsum ", 10);   add(item); 

you trying add item after setvisible true not displaying

solution:

add item first set frame visibility true

     frame.setsize(300,100);      setlayout(new flowlayout());      item = new jtextfield("lorem ipsum ", 10);      add(item);      frame.setvisible(true);
