Question

6.20: Word Count Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a "word" to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.

Input Notes:There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read. Don't use a string variable.

Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt. The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the program.

//Reader file = new File("C:/Users/jajraraj/Desktop/sample.txt");

FileReader fr = new FileReader ("C:/"+filename);   

BufferedReader br = new BufferedReader (fr);

String line = br.readLine();

int count = 0;

while (line != null) {

String []parts = line.split(" ");
