Comments in Java

Hello friends how are you, today in this blog i will teach you what is comment in Java, types of comment , details of each type of comment, how comment works and many programs using comment in a very simple way. 

Let's start

• It is used to explain the code to make it more readable.
• It is not considered as a part of program, in other word we can say that compiler ignores the comment.
• java comments are statements that are not executed by the compiler.

Types of comments in Java

• Single line comment
• Multiline comment

Single line comment

• It is used to comment only one line.
• Two forward slashes(//) is used for single line comment.
• Single line comment starts with double forward slashes.
• if in a program you want to comment only a single line then you can use single line comment.

//this is a single line comment
System.out.println("you are excellent");

Multiline comment

• Multiline comment is used to comment a block of code.
• Multiline comment starts with /* and ends with */.
• The text between /* and */ is not executed by the compiler.

class Easy
{
 public static void main(String[] args) 
 {
     /*
     This is multiline comment
     Write a program to add 
     two number and store it 
     in third number
     */
     int x,y=10,z=30;
     x=y+z;
     System.out.println("Add="+x);
 }
}
/*
### Output ###
Add=40
*/
