Inside of the main method and before the for each loop, create an ArrayList called sports that stores String types.

Add "Football" to sports.

Now add "Boxing" to sports.

The first for each loop in the code editor is missing the code that should be run. Inside of the for each loop, type:

System.out.println(sport);

Uncomment the incomplete for each loop towards the bottom and complete the loop by typing:

for ( String city : majorCities.keySet() ) {
}
