exception in thread "main" java .lang.UnsupportedClassVersionError:test (unsupported major.minor version 49.0)
at java.lang.ClassLoader.define(Class0(Native Method)
at java.lang.Class........

plz help me out to get rid of this error.tell me the solution to this problem as soon as possible.

I think you may have installed a second Java runtime.

TRy to run your program giving the explicit path to the java runtime in a command shell like this:

c:\testprogram\>"c:\program files\java\jre1.5.0_06\bin\java" -cp . MyProgram

If it works then check your Java Runtime Settings in the System Control Panel or just deinstall the other Java Runtime (should show up in the Application List).
