QUESTION 23:
Do you imagine that professional programmers ever get
== and equals confused?
Will pointA.equals(pointB) return the same true/false value as
pointB.equals(pointA) ?
Yes.
Perhaps you would like to practice? Assume that each row is independent of the others.
| code section | pointA == pointB | pointA.equals( pointB ) |
|---|---|---|
Point pointA = new Point( ); Point pointB = new Point( 0, 0 ); |
||
Point pointA = new Point( 21, 17 ); Point pointB = pointA; |
||
Point pointA = new Point( 21, 17 ); Point pointB = new Point( 7*3, 20-3 ); |
||
Point pointA = new Point( 21, 17 ); Point pointB = new Point( pointA ); |
||
Point pointA = new Point( 21, 17 ); Point pointB = new Point( 21, 17 ); pointA.move( 8, 12 ); |
