In this tutorial, You'll learn about java comments. The Java comments are statements of a java program that the java compiler and interpreter discards or ignores or simply does not execute.
Java Comments
The purpose of java comments is only to allow the programmer to insert some informative notes or descriptions to enhance the understandability of the java program. Sometimes, the Programmers used comments to hide the lines of programs.
Types of Java Comments
There are 3 types of comments in java.
- Single Line Comment
- Multi Line Comment
- Documentation Comment
Single Line Comment
The single line comment begins with two forward slashes (//). Any text after the // is ignored (not execute) by the compiler but in the same or one line only.
Syntax
// Single Line Comment written here
Example
import java.lang.*;
class Simple{
public static void main(String args[]){
System.out.println("HelloWorld"); // Print Hello World on Display.
}
}
Multi Line Comment
The multi line comment begins with /* and ends with */. Any text between this /* and */ is ignored (not execute) by the java compiler. It can be on different lines.
Syntax
/*
Multi Line
Comment Written Here
*/
Example
import java.lang.*;
class Simple{
public static void main(String args[]){
System.out.println("Codeamy.in");
/*
This is Multi
Line Comment
Example
*/
}
}
Documentation Comment
The comment begins with /** and ends with */. Documentation comment is used to automatically generate documentation. To create documentation, You need JDK tool 'javadoc'.
Syntax
/**
*Documentation
*Comment Written Here
*/
Example
/**
* The Java program
* to print Codeamy.in
*
* @author Veer Bhadra Solanki
* @version 1.0
* @since 2020-12-28
*/
import java.lang.*;
class Simple{
public static void main(String args[]){
System.out.println("Codeamy.in");
}
}
Happy Coding 😊
