}
}
1)- Multi-line Comment :-
Multi-line Comments are two or more than two line comments.
Sytanx :- /*

*/
int n=10;
System.out.println(n);
}
}
3)- Documentation Comment :-
The Documented Comments are used to create documentation API you need to use JAVA_doc tool. The JDK Java_doc automatically prepares document.
Syntax :- /**

Comment.
*/
Ex :-
/** here we are creating a add1 class */
public class add1
{
/** The add() method returns addition of given numbers.*/
public static int add(int a, int b)
{
return a+b;
}
/** The sub() method returns subtraction of given numbers.*/
public static int sub(int a, int b)
{
return a-b;
}
} Compile it by Javac tool :-
Create Documentation API by Javadoc tool :-
Javadoc add1.java
