- Keywords in java can be defined as reserved words or pre-defined words having their own importance and each keyword has its own importance and each keyword has its own functionality.
- Since keywords are reserved words used by the compiler so they cannot be used as variable names.
- If the keywords are used as the variable names it means that we are assigning a different meaning to the keyword which is not allowed.
- Java has a total of 51 keywords that have predefined meaning and are reserved for use by Java .49 keywords are currently used while the remaining 2 are no more used.
- All java keywords must be written in lower case.
