Playing sound thread sync with other codes ?

Hello all,

I have small sized mp3 files that i can play via Java using JLayerPlayer that takes the address of mp3 files , JLayerPlayer objects can be played creating threads and starting. The problem is when i have for example 9 sounds and i want it them to play in consecutively , so i put them in for loop like:

for(int i=1;i<mainNotaList.size()+1;i++)
{
neyBox1.arrangeNeyImage(mainNotaList.get(i-1));
showNames(mainNotaList.get(i-1));
txtAciklama.setText(mainNotaList.get(i-1).getAciklama());

Thread currentThread=new Thread(mainNotaList.get(i-1).getSoundLayer());
porteImgs[i].activate();
currentThread.start();
try {
currentThread.join();
} catch (InterruptedException ex) {
Logger.getLogger(Ney1View.class.getName()).log(Lev el.SEVERE, null, ex);
}
}

This codes starts and plays the sound consecutively but
this codes

neyBox1.arrangeNeyImage(mainNotaList.get(i-1));
showNames(mainNotaList.get(i-1));
txtAciklama.setText(mainNotaList.get(i-1).getAciklama());

are not being executed sync with the sound. they all are executed after all the sounds are played. How can i execute this codes first then play one sound, execute this codes play one sound...

I am new to java and the project due is this week , Desperately need solution.
Every suggestion helps. Thanks.
