A comment is a piece of text within a program that is not executed. It can be used to provide additional information to aid in understanding the code.
In Java, single-line comments are created with two consecutive forward slashes
// I am a single-line comment!System.out.println('Hello, world!');
A single-line comment can also be used to comment after a line of code:
System.out.println('Hello, world!'); // Me, too!
Multi-line comments are created by surrounding the lines with
/* at the beginning and
*/ at the end. Comments are good ways for a variety of reasons like explaining a code block or indicating some hints, etc.
/*And I am amulti-line comment!*/
