(2) The first line inside the enum should be a list of constants and then other things like methods, variables and constructors

(3) According to Java naming convention, it is recommended that we name constant with all capital letters. 

Example:—
    enum Color
          {
            RED, GREEN, BLUE;
           }
       public class Test
           {
        //Driver methods
      public static void main (String[ ]args) 
          }
       Color c1=Color.RED;
      System.out.println(c1) ;
     }
     }

Output:—
RED

Advantages of Object Oriented Programming - Learn Java - The Java Concepts

-
  Advantages of OOP:  Object-Oriented Programming have the following advantages over conventional procedural and other approaches :  1. OOP provides a clear modular structure for programs. This makes it good for defining abstract data types where implementation details are hidden and clear interfaces are defined.  2. OOP makes it easy to maintain and modify existing code as new objects can be created with small changes to existing ones. 3. OOP provides a good framework for code libraries where software components can be easily taken and modified by the programmer. This is particularly useful for developing graphical user interfaces applications.

Java Naming Conventions Java Naming Conventions Java is strictly a case sensitive programming language, where is Java applications there is a separate Recognization for lower case letters and for Upper case letters. To use lower case letters and Upper case letters in Java applications, Java has given a set of conventions All classes names, abstract classes names, interface names must be started with upper case letters and the sub sequent letters must also be upper case letters Ex: String, StringBuffer, InputStreamReader All Java variables names must be started with lower case letters buts the subsequent symbols must be Upper case letters Example: in, out, err, pageContext, bodyContent All the Java method names must be started with lower case letters but the subsequent Symbols must be Upper Case letters.

Advantage and Disadvantages of Top-down Programming - Learn Java - The Java Concepts Part

-
  Advantages of top-down programming : Programming team stays focused on the goal.  Everyone knows his or her job.  By the time the programming starts there are no questions.  Code is easier to follow, since it is written methodically and with purpose.  Disadvantages of top-down programming: Top-down approach may complicate testing, since nothing executable will exist until the end of the project.  You have to provide a clear goal description in advance because all decisions depend on it.
