Hi All,

Recently i was asked a question in an interview that when we provide command line parameter like -Xms or -Xmx while running a java program How jvm actually reads those parameters or How does jvm parse the parameters ?


Thanks.

I don't understand the question. Do you mean how does the JVM (and I'm not at all sure that it is the JVM) recognize those parameters?

Perhaps you should provide the question exactly as it was asked.

Isn't it funny how there's always time and money enough to do it WRONG?

Well, they all begin with "-X"; I suspect that's a help.
