What is thread polling in Java?
The process of testing a condition repeatedly till it becomes true is known as polling. Polling is usually implemented with the help of loops to check whether a particular condition is true or not. If it is true, certain action is taken. This waste many CPU cycles and makes the implementation inefficient.
What is run method in Java?
The run() method of thread class is called if the thread was constructed using a separate Runnable object otherwise this method does nothing and returns. When the run() method calls, the code specified in the run() method is executed. You can call the run() method multiple times.
What is multithreading explain with example?
Multithreading enables us to run multiple threads concurrently. For example in a web browser, we can have one thread which handles the user interface, and in parallel we can have another thread which fetches the data to be displayed. So multithreading improves the responsiveness of a system.
What is the purpose of multithreading?
Multithreading allows the execution of multiple parts of a program at the same time. These parts are known as threads and are lightweight processes available within the process. So multithreading leads to maximum utilization of the CPU by multitasking.
What is Java thread priority?
Thread priority in Java is a number assigned to a thread that is used by Thread scheduler to decide which thread should be allowed to execute. In Java, each thread is assigned a different priority that will decide the order (preference) in which it is scheduled for running.
What is notify () in Java?

What is thread pool and executor?
ThreadPoolExecutor is an ExecutorService to execute each submitted task using one of possibly several pooled threads, normally configured using Executors factory methods. It also provides various utility methods to check current threads statistics and control them.
What happens if you call run () directly?
The run method is just another method. If you call it directly, then it will execute not in another thread, but in the current thread. If start isn’t called, then the Thread created will never run. The main thread will finish and the Thread will be garbage collected.
What does start () do in Java?
Java Thread start() method The start() method of thread class is used to begin the execution of thread. The result of this method is two threads that are running concurrently: the current thread (which returns from the call to the start method) and the other thread (which executes its run method).
Which is the best definition of dispatchable generation?
Dispatchable generation refers to sources of electricity that can be dispatched on demand at the request of power grid operators, according to market needs. Dispatchable generators can adjust their power output according to an order.
What do you need to know about dispatchable location?
Dispatchable location information includes the street address of the caller and additional information, such as room or floor number, necessary to adequately locate the caller.
Which is an example of a dispatchable source of electricity?
A dispatchable source of electricity refers to an electrical power system, such as a power plant, that can be turned on or off; in other words they can adjust their power output supplied to the electrical grid on demand. Most conventional power sources such as coal or natural gas power plants are…
Why do we need a dispatchable power system?
Despite those periods of excess wind and solar power, because we lack an ability to store electricity for more than a few hours, dispatchablepower from the combustion of fossil fuels continues to bridge gaps in supply. BLOOM ENERGY DEBUTS HYDROGEN-POWERED ENERGY SERVERS
