Why I should use a JPanel?

Question

What\'s the difference between:

public class Test {

    public static void main(String[] args) {
        JButton button= new JButton(\"1\");
        button.         


        

Answer 1

There is basically no visual difference in your two examples, but the UI is too poor for exhibiting a difference. A JPanel is exactly what a panel is in real life, something used to display things inside it. It is generally used to contains different elements that you want to display in a given layout.
