Comments are basically lines that give us a brief description of the code written without getting interpreted by the compiler.
Let’s create a Comment in Java
A comment begins with 2 forward slashes. Let’s see an example to understand it better.
// This is a comment
Types of Comments
Comments can basically be submerged into the following types:
1. Single Line Comments
2. Multi Line Comments
Single Line Comments
The Single Line Comment is the easiest type of comment. It starts with 2 forward slashes and is further followed by an explanation.
It is used for some quick explanation of the code.
|// This program prints Hi|
Multi Line Comments
A comment spread over multiple lines is called a multi line comment. Let’s go over the following example to understand multi line comments.
|This program prints the sum of 2 variables|
|here a is 1 and b is 2|
|so c will be 3|
|int a = 1;|
|int b = 2;|
|int c = a + b;|
