2. T hreads are a way to achieve concurrent execution of tasks, allowing different parts of a program to run independently. Threads are instances of the Thread class or objects that implement the Runnable interface. T hreads are a fundamental part of concurrent programming. A thread is the smallest unit of execution within a process. Java provides built-in support for multithreading through the Thread class and the java.util.concurrent package.

3. Whenever we create a thread in Java, it always has some priority assigned to it. Priority can either be given by JVM while creating the thread or it can be given by the programmer explicitly.  Thread with the highest priority will get an execution chance prior to other threads. Suppose there are 3 threads t1, t2, and t3 with priorities 4, 6, and 1. So, thread t2 will execute first based on maximum priority 6 after that t1 will execute and then t3. The default priority for the main thread is always 5, it can be changed later.

4. Creating Multiple Thread

5. S ynchronization in java is a concept that deals with the coordination of multiple threads to ensure that they access shared resources in a safe and orderly manner. In a multithreaded environment, where multiple threads are executing concurrently, synchronization becomes crucial to avoid data inconsistency and potential race conditions. Java synchronization
