Respond to the following in a minimum of 175 words:

The purpose of this discussion is to explore concurrency, which refers to threads that run alongside each other during program execution, as opposed to running serially, or one after the other, and to discuss potential drawbacks and problems associated with concurrency.

Java™ provides built-in support for concurrent programming by allowing the running of multiple threads concurrently within a single program. A thread, also called a lightweight process, is a single sequential flow of programming operations with a definite beginning and end. During the lifetime of a thread, there is only a single point of execution. A thread by itself is not a program, because it cannot run on its own, instead all threads must run within a program.

Research and discuss with your classmates the benefits of concurrency in Java™. What are the potential drawbacks?
