Write a program that reads lines from a file and prints them out, removing all occurrences of a specified string from the lines.

LANGUAGE: Java

CHALLENGE:

Write a program that reads lines from a file and prints them out, removing all occurrences of a specified string from the lines.
For example, if the class that housed your program was called Exercise12_11, running this prompt on the command line:
java Exercise12_11 John filename
Would print out the contents of the file filename without any instances of the string John.
Your program should get the arguments from the command line.

SOLUTION:

import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;


public class RmvText {
   public static void main(String[] args) throws FileNotFoundException {
       String word = args[0];
       String filename = args[1];
       Scanner scan = new Scanner(new File(filename ));
       while(scan.hasNextLine()){
           String line = scan.nextLine();
           line = line.replaceAll(word," ");
           System.out.println(line);
       }
   }
