    Default Using the replace method?

    I am trying to write a program that takes the word Mississippi and replaces all the i's with !'s and all s's with $'s. It doesnt allow me to compile the code because it says something about a syntax error on token "!". Here is the code so far:

    public class Replace 
    {
    	public static void main(String[] args)
    	{
    		String word = "Mississippi" ;
    		String word2 = word.replace(i, !) ;
    		String word3 = word2.replace(s, $) ;
     
    		System.out.println(word3);
    	}
    }

    Could anyone help?

    Have you tried reading the Javadoc? There's an example which might help you figure out why you're getting the compile error.

    gah, embarrassing error. I really need to keep my methods straight

    Ummm...
    From String (Java Platform SE 6) and from the Java 7 reference whose link you posted:

    String replace(char oldChar, char newChar)
    Returns a new string resulting from replacing all occurrences of oldChar in this string with newChar
    .


    Cheers!
