Differences Between Method and Function

can any one explain clearly what is the difference between the Method and a Function, if possible by using some syntax and examples.

no difference according to me...

method is OO concept related to class
i.e. function written for a class = method

this is my wild guess...
as per my knowledge it hardly makes any difference.

Hi,
method should declares and defines within the class only. so it has access controlling mechanism. used in oops.
function declares and defines anywhere in the code. it has not access controlling. used in structured language.
even behavior is same.

thanks

hi,

In java function is call itself as a method.... there is not any difference in those thng.... it just using of terms...like in c++ we call it functins..and in java we call it as methods. In more simple terms Method does not take any arguement and it is invoked by method call
whereas function may or may not take the arguements?
Also Method does't return any thing but the function can return any thing

Thanks

both r same but method does't return any thing and function returns any thing

Function and Method both are same. But if it is declared outside of class it is function and if it is declared within class that is method.
In case of C++ it will support both functions and methods
But In case of Java there is no Functions concept only method is alloed.

hi,
look friend, according to u method does not return any value is like a wrong concept because it returns the value in java.
thanks

hey! dude u r right, method returns value....
Check the program

public class Hello {
public static int a() {
System.out.println("Hello to the World of OOPs....!");
return 0;
}
}

this method returns the value...

The terms [I]method[/I], [i]function[/i], [i]procedure[/i], [i]subroutine[/i], and [i]subprogram[/i] are all roughly synonymous, although the term [i]function[/i] is generally reserved for a subroutine that returns a value. Some languages like Fortran use slightly different syntax to define functions vs. procedures. For my part, I tend to use [i]method[/i] when I'm talking about a subroutine that's a class member and [i]function[/i] for subroutines that aren't class members, regardless of whether they return a value or not.

In C++ functions are also called using reference variables only..
