- Question
What is the name of the method used to start a thread execution?
Options- A. init();
- B. start();
- C. run();
- D. resume();
- Correct Answer
- start();
ExplanationOption B is Correct. The start() method causes this thread to begin execution; the Java Virtual Machine calls the run method of this thread.Option A is wrong. There is no init() method in the Thread class.
Option C is wrong. The run() method of a thread is like the main() method to an application. Starting the thread causes the object's run method to be called in that separately executing thread.
Option D is wrong. The resume() method is deprecated. It resumes a suspended thread.
