Finds the size of a file.

The length method of file class can be used for finding the size of a file. If the file object represents a directory the length method returns zero.

package io;

import java.io.File;

public class FileExample {
	public static void main(String[] args){
		File file = new File("d:\\temp\\test.txt");

		// Find the size of the file in bytes
		long value = file.length();

		// Convert the size in bytes to mega bytes.
		double sizeInMB =(double) value / 1024 / 1024;
		System.out.println(sizeInMB);
	}
}
