Which method can NOT be called directly in Java?

  1. main()

  2. finalize()

  3. System.gc()

  4. private methods of the same class

The correct answer is: finalize()

Finalize() is the only option that cannot be called directly in Java. This is because finalize() is used by the garbage collector to free up memory resources and cannot be called explicitly in the code. All other methods, including main(), System.gc(), and private methods of the same class, can be called directly in Java.
