Arrays grow when you add to them

An array gets bigger by itself when you store something past its end, so its size does not need to be decided in advance.

Evidence patterns

Pattern 0: predict a write one past the end of an array

predicts the array now has one more element

Item

int[] a = new int[3];
a[3] = 7;
System.out.println(a.length);

ExpectedArrayIndexOutOfBoundsException

Response4

Discriminators

vs a slip. Consistent across items; the learner treats arrays like lists. A slip is a single off-by-one index.
