28,694 PointsThe constructor is meant to set an object up for use. This means putting it's values in an initial state. To begin with, the PezDispen As for "mPezCount = MAX_PEZ", this is assignment. The value on the right hand side (MAX_PEZ) is placed into the variable on the left hand side (mPezCount). The PezDispenser is empty to begin with, and then it is set to be full.

Simon Coates
28,694 Pointsit sets the internal value for current number of pez to be the maximum value that the dispense can hold (as defined by the MAX_PEZ constant). It occurs within the load method. You create the dispenser (at which point it contains no pez - hence the assignment of 0 in the constructor), and then you can fill it (this is what the load method does).
