We’ll also look at mutability of objects, and how it interacts with expression-oriented programming. A statement is something that executes; an expression is something that evaluates to a value. STATEMENT VERSUS EXPRESSION Expressions are blocks of code that evaluate to a value. In Scala, some control blocks are also expressions. This means that if the control were to branch, each of these branches must evaluate to a value as well. The if clause is a great example; this checks a conditional expression and returns one expression or another, depending on the value of the conditional expression.

We placed it into the HashMap when x has a value of (1,1). This means it had a hash code of 32. We then move x to (2,2), changing its hash code to 64. Now when we try to look up the label in the map using x, it can’t be found because x was encoding with the hash bucket of 32, and it’s looking in the hash bucket for 64. Well, what if we try to look up the value using a new point, z, that still has a hash code of 32? It also fails, because x and z aren’t equal according to our rules. You see, a HashMap uses the hash at the time of insertion to store values but doesn’t update when an object’s state mutates.
