Null Check in Java 7.0

Monday, March 2nd, 2009
Null check is becoming easier in Java7.0. I hope most of you aware of this. I was reading one of the java blog and found the following is interesting there.Earlier Version of Java
			Car car = ...Integer tilt = null;
				if(car != null) {
					Sunroof sunroof = car.getSunroof();
					if(sunroof != null) {
						tilt = sunroof.getTilt();
					}
				}
		
In Java7.0, the above statement can be written as.
			Integer tilt = car?.getSunroof()?.getTilt();
