If you don't know what to return, make your method return nothing, i.e. make your method a void method. (also make it either handle an IOException or mention it in a throws clause).

kind regards,

I am Trying to Pass File name and Data as parameters to the method,

Which creates a file with that file name and writing data to that created file.

But i Don't know where i am Wrong....

Like Josah said:
1. If a file does not return a value, it's return type is void.
e.g. the main method does not return a value - hence it's called public static void main (String args[])

2. Handle exceptions using try, catch

try
{

//code that the program should try to do <-- the code of WriteToFile method should go here.

}
catch(Exception e)
{

//what the program should do if it could not do the above code.[/COLOR]
e.printStackTrace()//A stack trace basically lists all the points where the program went wrong and what caused things to go bad.

}

Thanks eLancaster and JosAH,

It is Working now..

any method in Java SHOULD have a return type....

if it is returning a particular object...then its class name would be the return type of the method

even if your function is not returning anything...the function should still have a return type..as "void"

for example, you very own main() method..does it return anything? no..still we declare it as

 public static [I]void[/I] main...

so in short, whatever method u r declaring...if it does not return anything, it should specify return type as void...like this

 
public void WriteToFile(....) { // do something

}
