I want to fetch the Java version in Linux in a single command.

I am new to awk so I am trying something like 

java -version|awk '{print$3}'

But that does not return the version. How would I fetch the 1.6.0_21 from the below Java version output?

java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)
