How to check the Java release version
To retrieve the Java release version number, use the standard System.getProperty() method:
System.getProperty("microedition.platform");
The returned string reads something like this:
Nokia5800d-1/20.0.012/sw_platform=S60;sw_platform_version=5.0;java_build_version=1.3.4
In the string, java_build_version indicates the Java release version, in this case 1.3.4.
