    Help!!!!!! Project due Tomorrow!!

    I have a project that i have no idea where to start with.

    The question is - Write a program that reads a line of text from the keyboard and then displays it without any punctions. Hint: create a string or punctuation character ",.:;'?!\"()" test to see if the next character of the line is not a substring of the punctuation string, then add it to the new string that does not contain punctuation.

    Any help is appreciated
    thanks

    No need to deal with it character by character or use substring etc. Basic regex will suffice. I'll leave it up to you to figure out how to read from keyboard etc.

    Code:
    public class Test {
    	public static void main(String[] args) {
    		try {
    			String s = "This is a sentence.  Here is a comma ','.  And a question mark '?'.  And some more crap: ,.:;'?!\"()";
    			System.out.println("Before: " + s);
    			s = s.replaceAll("[,.:;'?!\"()]", "");
    			System.out.println("After: " + s);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}	
    	}
    }
    PS. There are more punctuation characters than you have listed but I have just used the ones you mentioned.
