How do you control threads in Java?
In the current version of Java, you can stop a thread using a boolean volatile variable. If you remember, threads in Java start execution from the run() method and stop when it exits the run() method, either normally or due to any exception.

What are the different thread methods in Java?
Thread Methods:
- start(): start the thread.
- getState() – Returns the state of the thread.
- getName() – Returns the name of the thread.
- getPriority() – Returns the priority of the thread.
- sleep() – Stops the thread for the specified time.
- Join() – Stops the current thread until the called thread has finished.
How is a thread controlled?
Modern ways to suspend/stop a thread are by using a boolean flag and Thread. interrupt() method. Using a boolean flag: We can define a boolean variable that is used to stop/kill threads, say ‘exit’. Whenever we want to stop a thread, the ‘exit’ variable will be set to true.
What are the different lifecycle methods of threads?
Lifecycle of a thread (thread states) According to Sun, there are only 4 states in the thread lifecycle in Java: new, runnable, not runnable, and terminated. There is no running status.
What is yield() in Java?
A yield() method is a static method of the Thread class and can stop the currently executing thread and give other waiting threads of the same priority a chance. If in case there are no waiting threads or if all waiting threads have low priority, the same thread will continue its execution.
What is the main thread in programming?
When an application component starts and the application does not have any other components running, the Android system starts a new Linux process for the application with a single thread of execution. By default, all components of the same application run in the same process and thread (called the “main” thread).
How to control the behavior of a thread in Java?
Core Java provides complete control over the multi-threaded program. You can develop a multi-threaded program that can be suspended, resumed or completely stopped depending on your requirements. There are several static methods you can use on thread objects to control their behavior. The following table lists those methods:
How does a thread run in Java?
If the class extends the Thread class, the thread can be run by creating an instance of the class and calling its start() method: If the class implements the Runnable interface, the thread can be run by passing an instance of the class to a Thread’s constructor of the object and then calling the thread’s start() method:

What is the entry point of the thread class in Java?
The Thread class has the following important methods. We’ll also understand various thread states later in this tutorial. This method will start a new thread of execution by calling the run() method of the executable thread/object. This method is the entry point of the thread. Thread execution starts from this method.
