the "if" statement

I was confused in the "load(int pezAmount)" method. Is the "mPezAmount = newAmount" the "else" in the if statement?

1  if (newAmount > MAX_PEZ) {
2      throw new . . . ;
3  }
4  mPezCount = new Amount;
5  . . .

Technically line 4 is not the else... for the if... statement, because there is no else.... But from the practical point of view, yes, it could be considered such. If newAmount is greater than MAX_PEZ the program throws an exception and stops. If it's not, then the flow of control goes from line 1 to line 4. The code could be rewritten to put what follows in an else { . . . } statement, but for many that just makes it more complicated.
