Which containers use a FlowLayout as their default layout?

In Core Java, the correct answer is that Panel and Applet containers use FlowLayout as their default layout. The FlowLayout arranges components from left to right in a row until there is no more space, and then it moves to the next row.

It’s worth noting that the use of FlowLayout as the default layout manager for Panel and Applet has been consistent in older versions of Java. However, as of my last knowledge update in January 2022, the specific details may change in more recent Java versions. Always refer to the official Java documentation or the documentation specific to the Java version you are using for the most accurate and up-to-date information.
