                          A computer program can be defined as a collection of instructions to perform a specific
                        task.

                         The process of writing a program is called program coding or programming.
                         There are mainly two types of programming languages: procedural and object-oriented.

                         Java is an object-oriented and high-level programming language.
                         Java follows the Write Once Run Anywhere (WORA) principle.

                         A class can be defined as a user-defined blueprint or prototype that is used to create
                        objects.
                         BlueJ is an IDE designed for beginners.

                         An identifier is the name given to an object in a Java program.
                         Keywords are the reserved words that cannot be used as identifier names as they carry
                        a special meaning for the Java compiler.
                         A data type is used to define the size and type of value that a variable can store.

                         A literal denotes a constant value.
                         Variables are the memory locations used to store values.

                         A comment is a statement in a Java program that is not executed by the Java compiler.
                         An operator is a symbol that tells the compiler to perform specific mathematical or
                        logical calculations.

                 A.  Tick (✓) the correct option.
                     1.  Which of the following symbols are used to write comments in Java?

                       a. //                                            b. /** and */

                       c. /* and */                                     d. All of these
