Ace Java 2026: Rock Your 'Thinking in Java' Challenge!

The default layout manager used in a JFrame is BorderLayout. This layout arranges components in five regions north, south, east, west, and center. It is useful for creating simple and organized user interfaces with a header, footer, and main content. The other options (FlowLayout, GridLayout, and BoxLayout) are all valid layout managers but they are not the default for a JFrame. FlowLayout arranges components in a left-to-right, top-to-bottom flow. GridLayout arranges components in a grid of rows and columns, with each cell having equal size. BoxLayout arranges components in a single row or column. These options may be used depending on the desired layout for the user interface, but they require additional coding to implement as they are not the default in a JFrame.
