@Bill,
Understand my need to call a method in loop, to persist connection .

13 years ago

@William :

Dear William consider a scenario , you have a connection (object- encapsulated a authenticated session) to a server. by using connection object you have to send some commands to server and taking response from server, to make this connection alive ,persists you have to call a method periodical in a infinite loop, in mean time if you want to execute a command by using connection ,you have to stop infinite loop method, and start executing other method using same connection object connection. and when commands are completed you have to recall infinite loop method to make connection alive continuously.

Here my problem is how switch between methods (infinite loop method and other command methods how to stop a infinite loop method by run time argument) i cant use recursion methods,can't call a method inside a method).

Hope you got my point .

Regards
Gaurav

Loading and running single instance of class ,

It is possible in java to restrict a definite class loading ,if it is preciously running in a local host machine JVM,
i.e at one time only one process of the class running in JVM.

in this code i have to switch between two methods at run time useClient(int x) and contactInfo(EPPClient xy) at run time.

Dynamic Switching between two are more methods

I am very sorry for not using "[code]" and hope in future it will not happen,

Thanks for your kind response.
