In Java programming language, there are some keywords. The keywords are reserved words that have a special meaning and perform specific tasks. Note that these keywords cannot be used to name a constant or a variable as these are reserved words. In this case java compiler will show error. Here is a list of keywords used in this programming language:
Java Keywords
