How to iteratively add Components to a Swing GroupLayout ParallelGroup?

Question

Is there a way to iterate over a List of Components and add them to a ParallelGroup in Swing GroupLayout?

It seems difficult because there is no method to get hold

I can see what you're trying to do and your confusion. You can only use anonymous class syntax with the new operator. i.e

new LinkedList<String>() {
  {
     add("bar");
  }
};

However ParallelGroup instances can only be created with the factory method createParallelGroup(...).

You'll have to use a temporary reference to the parallel group:

ParallelGroup pGroup = gl
        .createParallelGroup(GroupLayout.Alignment.CENTER);
hGroup.addGroup(pGroup);
for (JCheckBox c : listCustomiseJCB) {
    pGroup.addComponent(c);
}
