Arrays are a collection of objects that are the
same type
 For example, 1000 ints
 Temperature over 5 days
int[] temperatures = new int[5];

// Count from 1 to 9
for (int i = 1; i < 10; i++) {
print (i);
}
// We could also use a while() loop
int i = 1;
while (i < 10) {
print (i);
i += 1;

With a growth mindset, we can improve our
skills through practicing.
Learning happens over time, not instantly.
The process of learning is uncomfortable
when we’re not competent yet.
