Which method is called when a thread starts executing?start()init()run()execute()
Solution 1
The method that is called when a thread starts executing is the start() method.
Here's a step-by-step explanation:
-
When a thread is instantiated using the Thread class, the thread is in the new state and not yet started.
-
To start the thread, the start() method is called. This method is a part of the Thread class in Java.
-
The start() method does two things: it starts the thread and calls the run() method. The run() method contains the code that is executed in the new thread.
-
The init() method is not related to thread execution. It's typically used to initialize an applet in Java.
-
The execute() method is not a standard method in the Thread class. It might be used in specific contexts or frameworks, but it's not part of the standard process of starting a thread.
So, the correct answer is start().
Solution 2
The method that is called when a thread starts executing is the start() method.
Here are the steps of how it works:
-
An object of a class is created that extends the Thread class or implements the Runnable interface. This class has the run() method which contains the code that will be executed in the thread.
-
The start() method is called on the object created in step 1. This method is a built-in method of the Thread class and it's used
Solution 3
The method that is called when a thread starts executing is the start() method.
Here's a step-by-step explanation:
-
When a thread is instantiated using the Thread class in Java, the thread is in the new state.
-
The start() method is then called on this instance of the thread to move it from the new state to the runnable state. This method is also responsible for performing all the necessary actions to set up the thread for execution, such as allocating memory and stack.
-
Once the thread is in the runnable state, the thread scheduler can then choose to execute this thread based on thread priorities.
-
When the thread is chosen for execution, the run() method is called. This method contains the code that will be executed in the new thread's context.
-
The execute() method does not exist in the Thread class in Java, so it's not applicable in this context.
So, the correct answer is the start() method.
Solution 4
The method that is called when a thread starts executing is the start() method.
Here's a step-by-step explanation:
-
When a thread is instantiated using the Thread class, the thread is in the new state.
-
The start() method is called on this instance to begin the execution of the thread. This causes the thread to change its state from new to runnable.
-
The Java Virtual Machine calls the run() method of this thread causing it to move to the running state.
-
The run() method contains the code that constitutes the new thread's "task" or "job".
-
Once the run() method completes, the thread dies and cannot be restarted with another call to start().
So, while the run() method contains the code that the thread is supposed to execute, it's the start() method that is called to begin the execution of the thread.
Solution 5
The method that is called when a thread starts executing is the start() method.
Here's a step-by-step explanation:
-
When a thread is instantiated using the Thread class, the thread is in the new state.
-
The start() method is called on this instance to begin the execution of the thread. This causes the thread to change its state from new to runnable.
-
The Java Virtual Machine calls the run() method of this thread causing it to move to the running state.
-
The execute() method does not exist in the Thread class in Java.
So, the correct answer is start().
Solution 6
The method that is called when a thread starts executing is the start() method.
Here's a step-by-step explanation:
-
When a thread is instantiated using the Thread class, the thread is in the new state.
-
The start() method is called on the thread instance to begin its execution. This method is responsible for starting a thread and calling the run() method. The thread is in the runnable state after the start() method is called.
-
The run() method contains the code that is executed in the new thread. This method is called after the thread's start() method is called, and the thread is moved from the runnable state to the running state.
-
The init() method is not related to the execution of threads. It's typically used in applets to initialize variables, not threads.
-
The execute() method is not a standard method in the Thread class in Java. It might be used in some specific contexts or classes, but it's not the method called when a thread starts executing in general.
So, the correct answer is start().
Solution 7
The method that is called when a thread starts executing is start(). Here are the steps of how it works in a thread's lifecycle:
-
An instance of a class is created that extends the Thread class or implements the Runnable interface. This instance represents a single thread in your program.
-
The start() method is called on this instance. This method is a part of the Thread class and it's used to begin the execution of a thread. Internally, it calls the run() method of the Thread class.
-
The run() method contains the code that needs to be executed in a thread. It's like the entry point of the thread, similar to the main() method for the application.
-
The thread stops executing once it has completed the code inside the run() method.
So, the correct answer is start().
