Select the correct answerWhich of these are integer constants defined in ActionEvent class?OptionsSHIFT_MASKCTRL_MASKALT_MASKAll of the mentioned

Break Down the Problem

1. Identify the options provided in the question.
2. Clarify the concept of integer constants in the context of the ActionEvent class.

Relevant Concepts

• The ActionEvent class in Java contains various constants that are related to action events, including key events. These constants are often used for handling keyboard and mouse actions.

Analysis and Detail

1. SHIFT_MASK: This is a constant integer that represents the state of the Shift key. It indicates whether the Shift key is pressed during an event.
2. CTRL_MASK: Similarly, this constant represents the state of the Control (Ctrl) key. It is used to check if the Ctrl key is pressed during an action event.
3. ALT_MASK: This constant indicates the state of the Alt key, allowing the detection of whether the Alt key is pressed.
4. All of the mentioned: This option suggests that all the previous options are integer constants defined in the ActionEvent class.

Verify and Summarize

All three options (SHIFT_MASK, CTRL_MASK, ALT_MASK) are indeed integer constants defined in the ActionEvent class. Therefore, the option "All of the mentioned" is correct.

Final Answer

All of the mentioned.
