What is the use of keywords in Java?

Keywords or Reserved words are the words in a language that are used for some internal process or represent some predefined actions. These words are therefore not allowed to use as a variable names or objects. Doing this will result into a compile time error. Java also contains a list of reserved words or keywords.
