                      Character sets in Java consist of Alphabets, Digits, Operators and Delimiters.
                      There are two types of encoding procedures – ASCII CODE and UNICODE.

                      Escape sequences are non-graphical characters preceded by backslash to perform some specific task.
                      A token is the smallest individual element of a java program that is meaningful to the compiler and takes part in
                      effective execution of the program.
                      Keywords are the pre-defined words that are reserved by Java compiler for a specific purpose.

                      Variable is name of reserved area allocated in computer memory.
                      Literals or constants are values cannot be changed once assigned and used by programmers.
                      Identifiers are user-defined names consisting of any sequence of letters and digits starting with either a letter or
                      underscore (_).

                      Operators are special symbols that signify the compiler to perform some specific mathematical or
                      non-mathematical operations on one or more operands.
                      Data types specifies the size and type of values that can be stored in an identifier.
                      Type conversion is a process of changing one type value to another type

                      Boolean data type cannot be converted to any other data types or vice versa.
