How to get JRE or JDK version programmatically?

Hi,

I'm using eclipse 3.1 and want to get the JRE or JDK version programmatically

I wrote

System.getProperties();

System.getProperty("java.version");

It's not giving any errors, it's working fine but it prints empty values

does any one has any idea about this? and how to do it in another way?
