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 | |
| System.out.println("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; | |
| System.out.println(c); |
OUTPUT:
3
