How is concurrency mentioned in the context of AWT/Swing and SWT?

SWT supports multiple threads updating the display
AWT/Swing uses a multi-threaded rendering approach
SWT throws an exception if you try to update the display from multiple threads
AWT/Swing allows multiple threads to update the display without issues

The correct answer is: SWT throws an exception if you try to update the display from multiple threads

Thread safety is an important aspect in user interface frameworks such as AWT/Swing and SWT. This means that only one thread should be responsible for updating and manipulating the components on the screen at a time. Option A is incorrect because while SWT does support multiple threads, it still requires proper synchronization to update the display. Option B is incorrect because AWT/Swing actually uses a single-threaded rendering approach. Option D is incorrect because it is actually not recommended to have multiple threads updating the display in AWT/Swing as it can lead to unexpected behavior and potential race conditions. Option C is the correct answer because SWT explicitly throws an exception to prevent multiple threads from updating the display at the same time, ensuring thread safety.
