TAKING VALUES AS ARGUMENTS

                 Until now, we have been initialising variables before using them. However, Java also allows us
                 to obtain variable values from the user at runtime. You can do this by passing arguments into
                 the main() method. We can accept a single value or multiple values by separating them with
                 commas, as shown below:
                 public class Arguments
                 {
                     public static void main(int roll_no, String name)
                     {

                         System.out.println("Roll number is: " + roll_no);
                         System.out.println("Name is: " + name);
                     }
                 }
                 When we  run  the above  program  in BlueJ, a
                 Method Call dialog box will appear,  prompting
                 you to enter the necessary arguments.

                                                                After  entering  the  value of the arguments,  click
                                                                on the OK button. The output will appear in the
                                                                terminal window.

                 Program 4: Write a program in Java to print the area and perimeter of the square.
                 public class SquareProperties {
                     public static void main(float side) {

                     float Area=side*side;
                     float Perimeter=4 * side;
                     System.out.println("Area of the square: " + Area);

                     System.out.println("Perimeter of the square: " + Perimeter);
                     }
                 }
