How can I get all the components of a panel in Java Swing?

Question

Is there any method like foreach in C# to deal all the child components of a JPanel?

Before asking, sometimes trying the obvious is worth it... :) — Steph, Mar 31 '13 at 08:19
you know that there's the api doc, do you :-) Hint: look also at the methods inherited from super. — kleopatra, Mar 31 '13 at 09:09

You may use the method getComponents:

Component[] components = jpanel.getComponents();

This will get the child components, but not those components' children. For example, if your panel has containers such as CollapsiblePanel, the set `components` will contain a reference to that CollapsiblePanel, but not its child components. – Jonathan E. Landrum Oct 21 '20 at 15:25

if you have more than one JPanel and you want to get all components Name try this:

public void getAllComponetsNameInJPanels(JPanel... panels) {
    Component[] components;
    String componentName;
    for (JPanel panel : panels) {
        components = panel.getComponents();            
        for (Component compo : components) {
            componentName = compo.getClass().getName();
            System.out.println(compo.getClass().getName().substring(componentName.indexOf("swing.") + "swing.".length(), componentName.length()));
        }
        System.out.println("=====================");
    }
}
