Learning Java/Fundamental exercises

1. Fix It!

Fix this code so it compiles and runs correctly (your file name is Main.java)

private class main {
	private static int main() {
		system.out.println('Hello World!')
		return 0
	}
}

2. A Full WaterVehicle, Ship, etc.

This exercise comprises of a base class WaterVehicle. It will also have a class Ship, a class Boat, a class WaterAirplane, and a class Submarine.

WaterVehicle Methods:

updateSpeed(int) will update the speed to a valid speed - higher than minSpeed and lower than maxSpeed

You can choose what to use.

Note: Ship, Boat, and WaterAirplane should extend WaterVehicle.

When you are done, you can create a main class to run your program. For example, the main class could create an instance of WaterAirplane and try using the methods.
