File Information Lab

Write a program that asks the user for a file name (or path). Your program should then open that specific file. (Assume the file will be .txt). Your program should then calculate the following information based on the specified text file:

%u3000

1. The number of lines in the file

2. The total number of words in the file

3. The number of characters in the file (not including spaces)

Once the information is calculated, print the data to the screen and also to a new file called results.txt.

BufferedReader br = null;

br = new BufferedReader(new FileReader(input));

String line;

int noline = 0,nochar = 0,noword = 0;

while((line = br.readLine()) != null){

noline++;

for(char c:line.toCharArray()){

if(c != ' ')

nochar++;

}

noword += line.split(" ").length;

}

br.close();

String output = "No of lines "+noline+" No of words "+noword+" No of characters "+nochar;

FileWriter fw = new FileWriter("result.txt");

BufferedWriter bw = new BufferedWriter(fw);

bw.write(output);

bw.close();

System.out.println(output);

}
