Description

A method, that can replace strings (keys) in a file would be very useful.

For example if you have a file with the following text:

The packet must arrive between @dateFrom and @dateTo. 

You can now replace the "keys" with a value of your choice..

Perhaps something like this:

	
public static void replaceStrings(File inputFile, File outputFile, List<KeyValuePair<String, String>> replacements) throws IOException{
		BufferedReader in = new BufferedReader(new FileReader(inputFile));
		BufferedWriter out = new BufferedWriter(new FileWriter(outputFile));
		
		String line;
		
		while ((line = in.readLine()) != null) {
			for(KeyValuePair<String, String> kvp : replacements){
				line = line.replace(kvp.getKey(), kvp.getValue());
			}
			out.write(line);
			out.newLine();
		}
		out.flush();
		out.close();
		in.close();
	}

I think it should also be possible, to replace the strings in the inputfile so you don't have to create a new file (outputfile)
