Put your labels in to LinkList or array Then you can access those array or linkList on a loop

If you cannot change the labels names / put them into an array you can make an array of references to the labels and fill it at the beginning of your program with the list of your labels.

If you are talking about Java labels, you can use a switch statement instead. If you are talking about objects such as a JLabel, use an array or ArrayList.

'Access to labels' is kinda vague. Are you referring to different instances of java.awt.label? If so you can simply loop over them when they're in a list with a for-each statement.

How about using List or an array

List<JLabel> labels = new ArrayList<JLabel>();
labels.get(index);

Change those labels to be an array, and access it using an index.

For example:

JLabel[] labels = new JLabel[10];
for (int i = 0; i < labels.length; ++i) {
    labels[i] = new JLabel("Label " + i);
}
for (int i = 0; i < labels.length; ++i) {
    // access each label.
}
