                  17                 System.out.println("Sum of the numbers: "+sum);

                  18                    System.out.println("Average: "+avg);

                  20          }
                 You will get the following output:




















                 Here,  the execution  starts with the statement  “class  sum_and_average”  and  continues  till  the  end in a
                 sequential manner.


                 8.1.2 Conditional Flow of Control
                 When according to the need of the programmer, the flow of a program is altered depending on a condition, it is
                 known as the conditional flow of control. In other words, the program control executes the required statement
                 depending on the condition stated.
                 Java provides various procedures to control the flow a program according to the need, which are given below:

                 •  if statement
                 •  if-else statement
                 •  Multiple if statements




                                                                                     Conditional Constructs in Java  157
