Concepts Tested in this Program:

Error Handling

Text I/O

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 RmvText, running this prompt on the command line:

java RmvText 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.

Please include a screen snapshot of the output.

Must include flowchart, pseudocode, and UML diagram

Name your program’s file as RmvText.java

SAMPLE RUN #1: java RmvText going input

Explanation / Answer

import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; public class RmvText { public static void main(String[] args) throws FileNotFoundException { Scanner fin = new Scanner(new File(args[1])); while (fin.hasNextLine()) { System.out.println(fin.nextLine().replaceAll(args[0], "")); } fin.close(); } }
