Annotations is structured information added to program source code. LikeComments, they can be sprinkled throughout a program and attached to anyVariable, method, expression, or other program element. Unlike comments,They has structure, thus making them easier to machine process.Annotations are structured information that is attached to the source code, like annotations, scattered across the program. Annotations can be attached to any variable, a method, an expression, or other program element. B

reader wants to do when he or she intends to learn a new language, and, of course, to write a few small programs to familiarize themselves with the grammar. However, many of the tutorials are only one or two lines of miniature code examples, just enough to demonstrate a feature, but not a single, useful program. If the language also has a built-in shell (or interpreter), such as Ruby, Groovy, and Scala, then the trend is becoming more pronounced.For

state at which the thread is eligible to run. In fact, this three-state combination is one, and its common denominator is that the thread is still alive, but there is no condition to run at the moment. In other words, it is operational, but if an event occurs, he may return to the operational state.5. Death state: When the thread's run () method finishes, it is considered dead. This thread object may be alive, but it is not a separate thread. Once a thread dies, it cannot be resurrected. If you
