Smart Programming Techniques

What is programming language?

● A language is used to create programs for management and communications of machines or computers.

● A programming language is a formal computer language designed to communicate instructions to a machine or particularly a computer.

What is the use of it?

● Programs are created through programming languages to manage and control the behavior and output of a machine or computer through accurate commands and algorithms, similar to the human communication process.

● Programming languages can be used to create programs to control the behavior of a machine.

Similar like Human Languages

What are the similarities?

Have you any Ideas?


● Keywords

● Keywords in programming Language○ class, return, default, switch, struct, continue, etc...

● Keywords in English Language○ I, am, is, are, this, that, etc...


● Constants or Literals

● Constants in programming Language○ “XYZ”, 10.25, 56, ‘A’, False, etc...

● Constants in English Language○ XYZ, 54.56, 28, A, Yes, etc...


● Operators

● Operators in programming Language○ +, -, &&, %, ++, <, >=, =, +=, etc...

● Operators in English Language○ +, *, OR, <, >, etc...


● Data Types

● Data Types in programming Language○ int, float, string, char, class, etc...

● Data Types in English Language○ number, date, decimal, string, etc...


● Syntax● Syntax in programming Language

○ If (condition){statements

}● Grammar in English Language

○ subject verb direct object indirect object

Programming as a career option

● Programming is one of the most fundamental skill any IT student must learn.

● Based on that one can apply for the job of programmer.● In current IT environment, Programming as a career

option has tremendous opportunities.● For that you have to be prepare yourself.● A lot of graduates aim to become a programmer but not

everyone succeeds to make a good career in programming.

Why Smart Programming Techniques?

● While the demand for programmers still remain very high and lot of graduates apply for programming jobs, only a few are actually appropriately skilled to become programmers.

● There are lot of programmers in IT industry, but only a few GOOD programmers.

● To fill the gap for such good programmers we have to learn smart programming techniques. It will make you an exceptional programmer and not just some ordinary average coder.


What makes you an exceptional programmer?

Any guesses ?


● Consistent Formatting or Style● “Programs are meant to be read by humans and only

incidentally for computers to execute.”● The quality of your code is not just in its execution but

also in its appearance.● Coding style is made up of numerous small decisions

based on the language.● Consistent formatting is how your code looks, plain and

simple to understand.


● Conventions and Comment/Document ● Coding conventions are a set of guidelines for a

programming language that recommend programming style, practices, and methods for each aspect of a program written in that language.

● These conventions usually cover file organization, indentation, comments, declarations, statements, whitespace, naming conventions, programming practices, programming principles, programming rules of thumb, architectural best practices, etc.


● Conventions and Comment/Document ● There will always be a time in which you have to return

to your code. Regardless, looking at your own code after six months is almost as bad as looking at someone else's code. To avoid such things you have to leave comments inside your code.

● Comments are little snippets of text embedded inside your code for leaving information about your code that are ignored by the compiler or interpreter.


● Efficient and Error Prone● Efficient programming is programming in a manner

that, when the program is executed, uses a low amount of overall resources pertaining to computer hardware.

● A program is designed by a human being, and different human beings may use different sequences of codes to perform particular tasks.

● If an exception is raised, which has not been handled by programmer then program execution can get terminated and system prints a non user friendly error message.


● Efficient and Error Prone● if ( "red".equals(color) || "green".equals(color) ||

"blue".equals(color) ) { System.out.println("This is a primary color");}

● if ( "red|green|blue".indexOf(color)>=0 ) { System.out.println("This is a primary color");}

● Always use exception handling technique to manage all possible errors and exceptions.○ try-catch, try-except etc.


● Reusable and Extensible● Try to think more abstractly and use Interfaces and

Abstract classes.● Try to reduce coupling.● Make a method that do just one thing. Be more

modular.● Write code like your code is an External API.● Always return something from your method. It helps to

make it extensible.● Always use default arguments inside your method

when data of those arguments are not fixed.


● Maintainable● Maintainability involves a system of continuous

improvement - learning from the past in order to improve the ability to maintain systems, or improve reliability of systems based on maintenance experience.

● Maintainability index is calculated with the certain formula from line of codes.
