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

Question

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

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

Answer 1

You may use the method getComponents:

Component[] components = jpanel.getComponents();

Answer 2

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("=====================");
    }
}
