how can i make labels "listen" to changes (in a String[] array for example) ??

i mean, i have an array that is updated whenever a change occurs to a server (that i monitor)

i want the labels to be "in sync" with the array content

can i do that ?

You need to keep an association between the JLabels and the array indexes. Storing the JLabels in their own array would be easiest. After retrieving the index as I have already shown, you simply retrieve the JLabel and change its text:
