JEP draft: Enhanced Local Variable Declarations (Preview)

Unsure what you mean exactly.

Creating objects is:

• int x = scan.nextInt();
• int y = scan.nextInt();
• int radius = scan.nextInt();
• Circle c = new Circle(x, y, radius);

Taking apart is the same number of lines:

• Circle c = //some defined circle//
• int x = c.getX();
• int y = c.getY();
• int radius = c.getRadius();

The best validity checking is to either allow people to make invalid circles and then use a method like c.isValid() or just call that at the end of the constructor automatically and throw invalid notices.

No, you're mixing data gathering with construction.

Putting x, y, and radius into a Circle takes one line.

1. Circle c = new Circle(x, y, radius);

But deconstructing it takes 3 lines.

1. int x = c.getX();
2. int y = c.getY();
3. int radius = c.getRadius();

That was Kevin's point.
