    There is no variable named type, perhaps you meant to use typeH instead.
    Also, it is almost never a good idea to compare String with ==. String are objects, so you should use the .equals() method instead.

    Most likely because typeH has not been initalized. Look at this code:
    if(input.nextLine().toLowerCase().contains("s")) {
    		typeH = "salaried";
    	} else if(input.nextLine().toLowerCase().contains("h")) {
    		typeH = "hourly";
    	}
    The Scanner.nextLine() method moves the pointer. So every time you call the nextLine() method, you are getting a different line. Is that what you intend on doing? What you should do is create a local String variable called line, or something, set line = input.nextLine(), and then use that in your if/else statements instead.

    When i execute it.
    --------------------Configuration: <Default>--------------------
    Hello! Welcome to Employee Database
    If Employee is salaried enter S. Otherwise enter H for hourly
    h

    it stays at this indefinitely, so there is something wrong with the if loops

    That shouldn't even compile.
    } else if()) {
    Not only is the if statement empty, but there is an extra bracket.
    Furthermore:
    private string line;
    string should be a capital S: String
