    Don't use the comparison operator, '==', to determine the equality of String objects. Use the equals method, e.g.:

    if ( thisString.equals( thatString ) )

    First thing's first: firm=="ford" is not correct. Strings (like all objects) should be compared using the .equals() method, not double equals. So, instead, you want: firm.equals("ford")

    Change that and see what happens.
