Question

a. In your own words, explain what is meant by good programming practice. Give two examples, one with good programming practice and one without good programming practice

Note:java Programming Language

Answer 1

Good programming practice means your programme code will be in well manner means you have to follow all the programming conventions like :

1)- Using naming conventions

2)- Ordering Class Members by Scopes

3)- Class members should be private

4)- Using Underscores in Numeric Literals

5)- Avoid Empty Catch Blocks

6)- Using StringBuilder or StringBuffer instead of String Concatenation

7)- Using Enums or Constant class instead of constant Interface

8)- Avoid Redundant Initialization (0-false-null)

9)- Using Interface Reference to Collections

10)- avoid using for loops with indexes

Example of good programming practice

public class Employee_Details // Naming conventions

{

private int Employee_ID;

private String Employee_Name; // class members should be private and use underscore between two name

Employee_Details(int ID, String Name) //use a constructor for accesing the private data or use public function

{

Employee_ID=ID;

Employee_Name=Name;

}

public static void main(String args[])

{

Employee_Details ob=new Employee_Details(23,"Rohit");

}

Example of bad programming style

class Abc //without using a valuable name of the class

{

int a=5; // without using naming conventions

int b=3;

public static void mian(String args[])

{

int c=a+b;

System.out.println(c);

}

}

*Note=>  Program will run in both conditon but by using conventions your program is understandable to your team member and they will continue your program in case of your absence
