thread is a flow of control within a program. A thread is similar to the more familiar notion of a process, except that multiple threads within the same application share much of the same state--in particular, they run in the same address space. It's not unlike a golf course, which can be used by many players at the same time. Sharing the same address space means that threads share instance variables, but not local variables

A new thread is born when we create an instance of the java.lang.Thread class. The Thread object represents a real thread in the Java interpreter and serves as a handle for controlling and synchronizing its execution. With it, we can start the thread, stop the thread, or suspend it temporarily.
