swing - Java GUI not appearing after implementing socket methods -

i no errors in code. code works fine long code within start method, created, commented out. unsure why happening. have tried moving code around not solve issue. why code within start method preventing gui showing on screen?

it looks me never getting gui portion of code. may want use multi-threading here, seem aiming for. in constructor, calling start method--all fine , far--and seems execute expect it. however, when call search() @ end of start(), enters infinite loop (the parameter being true). loop logic preventing return search(), thereby return start(), , constructor. hope helps, , best of luck you!
