Can we put the apex class in map as key and value?

Hi Naman

Yes you can put an instance of apex class in salesforce maps.

i try the following code and it doesnot gives an error to me:

public class help{

map<DarkJedi, integer> testMap;

public help(){
testMap = new map<DarkJedi, integer>();
}
}

Here DarkJedi is an apex class stored in my salesforce org.

Hope it helps

Thanks
