0:09 Welcome back to Code Chef. What if you
0:10 could make your code easier to
0:13 understand for yourself and others?
0:15 Today, we'll explore comments and naming
0:17 conventions in Java. Small but powerful
0:19 practices that help keep your code clean
0:22 and readable. Think of writing comments
0:25 like adding sticky notes to a recipe.
0:27 When cooking a complex dish, a note
0:29 like, "Add salt slowly" helps you or
0:32 others remember why that step matters.
0:34 Similarly, comments in code explain what
0:36 the code does without affecting how the
0:39 computer runs it. A comment in Java is a
0:41 line or block of text ignored by the
0:44 computer during execution.
0:45 It's written for humans to understand
0:48 the purpose of code. Good naming
0:50 conventions use descriptive and
0:52 meaningful names for variables and
0:54 methods to improve readability. Here's a
0:57 simple Java example. The first two lines
0:59 are comments that explain the purpose.
1:01 The variable names first number and
1:03 second number are descriptive. After
1:05 compiling and running the program, the
1:09 output will be 1020. Did you know Java
1:11 supports two types of comments? Single
1:13 line comments starting with double slash
1:15 and multi-line comments enclosed between
1:18 slashaststerisk and asterisk slash. For
1:20 example, comments don't affect program
1:22 output and help keep your code
1:25 organized. Now it's your turn. Try this
1:27 beginner friendly problem on Code Chef.
1:30 Variable naming practice. Write a
1:32 program that declares variables with
1:33 meaningful names and prints their
1:37 values. Today you learned comments help
1:38 explain your code without affecting execution.
1:40 execution.
1:42 Meaningful variable names make your code
1:45 easy to understand. Use single line and
1:48 multi-line comments for clarity. Code
