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.
