Great work! What did we learn so far?
- For Loops: used to repeatedly run a block of code
- For Each Loops: a concise version of a for loop
- ArrayList: stores a list of data
- HashMap: stores keys and associated values like a dictionary
Instructions
1.
Inside of the main
method and before the for each
loop, create an ArrayList called sports
that stores String
types.
2.
Add "Football"
to sports
.
3.
Now add "Boxing"
to sports
.
4.
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);
5.
Uncomment the incomplete for each
loop towards the bottom and complete the loop by typing:
for ( String city : majorCities.keySet() ) { }
