    It seems silly that a Short of value 1 is not equal to an Integer of type 1.

    I think this is pretty unintuitive feature - maybe they should have said ’screw backward compatibility’ to avoid it.

    Nice vid though!

    The second one is …
    The second one is crazy as well - does the name resolution happen when URLs are constructed/specified, or truly during the equals() method? If so, that’s quite the WTF!, since equals is called very often when dealing with sets… this implies that adding a URL to a set containing 1,000,000 URLs already will cause all of them resolved which makes no sense.

    distance=speed * …
    distance=speed * time
    for example, if a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles. write a program that asks for the speed ofa vehicle(in miles per hour) and the number of hours it has traveled. it should use a loop to display the distance a vehicle is traveling at 40 mph for a 3 hour time period. it should display a report similar to the one that follows:

    hour - 1 distance - 40
    hour- 2 distance- 80
    hour- 3 distance - 120
