Welcome back to Code Chef. What if you

could make your code easier to

understand for yourself and others?

Today, we'll explore comments and naming

conventions in Java. Small but powerful

practices that help keep your code clean

and readable. Think of writing comments

like adding sticky notes to a recipe.

When cooking a complex dish, a note

like, "Add salt slowly" helps you or

others remember why that step matters.

Similarly, comments in code explain what

the code does without affecting how the

computer runs it. A comment in Java is a

line or block of text ignored by the

computer during execution.

It's written for humans to understand

the purpose of code. Good naming

conventions use descriptive and

meaningful names for variables and

methods to improve readability. Here's a

simple Java example. The first two lines

are comments that explain the purpose.

The variable names first number and

second number are descriptive. After

compiling and running the program, the

output will be 1020. Did you know Java

supports two types of comments? Single

line comments starting with double slash

and multi-line comments enclosed between

slashaststerisk and asterisk slash. For

example, comments don't affect program

output and help keep your code

organized. Now it's your turn. Try this

beginner friendly problem on Code Chef.

Variable naming practice. Write a

program that declares variables with

meaningful names and prints their

values. Today you learned comments help

explain your code without affecting execution.

execution.

Meaningful variable names make your code

easy to understand. Use single line and

multi-line comments for clarity. Code

debug repeat. Build mastery with Code Chef.
