Peek view of Java 7.0 (Dolphin)

Here are some interesting features of Java 7.0

Using array syntax for collections access.

For example, instead of writing this:

List content = new ArrayList(10);

content.add(0, "Bean");

content.add(1, "Picks");

String name = content.get(0);

you will be writing..

List content = new ArrayList(10);

content[0] = "Bean";

content[1] = "Picks";

String name = content[0];

You can also initialize your List as

ArrayList content = {"Bean", "Picks", "Techno", "Blog"}

Most of the time we write so much code for accessing the getters and setters of beans. Consider you have a bean called Point, we generally write..

Point p = new Point();

p.setX(56);

p.setY(87);

int z = p.getX();

Now, with Dolphin, you could write

Point p = new Point();

p->X = 56;

p->Y = 87;

int z = p->X;

and your Point class will now look like this :

public class Point {

  public int property x;

  public int property y;

}

Cool. Isn’t it?
