x and y referenced in place of this.x and this.y On page 124, the sample code for step 3 reads: public double DistanceTo(Point other) { int xDiff = x - other.x; int yDiff = y - other.y; } It should read: public double DistanceTo(Point other) { int xDiff = this.x - other.x; int yDiff = this.y - other.y; }Ths sample code for step 4 reads: public double DistanceTo(Point other) { int xDiff = x - other.x; int yDiff = y - other.y; return Math.Sqrt(xDiff * xDiff + yDiff * yDiff); } It should read: public double DistanceTo(Point other) { int xDiff = this.x - other.x; int yDiff = this.y - other.y; return Math.Sqrt(xDiff * xDiff + yDiff * yDiff); }

defaultDate should be default Date On page 165, the first sentence of step 7 contains the words defaultDate twice. The second instance needs to have a space between default and Date.
