Well the String itself is implemented at a char array, so just count the chars. Then there is a little overhead elsewhere to track it's location. A file could be more complex. You could just read it out byte by byte and find out.

I really couldnt get your answer. i am able to count the charecters of the string. but i couldnt find any method to find the memeory it would occupy. Do you mean the physical address of the String object in memory?

If you are referring to the AMOUNT of memory, rather than the LOCATION in memory, each char is 2 bytes long in Java. So if a String has 10 characters, it occupies 20 bytes, plus whatever overhead is needed for the String class itself. HTH Layne
