I noticed you are trying to say 'complier or jvm' for some functionalities. It would be good and more clear if you are more specific while trying to say complier or jvm.

hey, I didn't understand "wrapper class" and " to string " topic.

1> java is popular coz its have strong API

[@krams915]

The first two reasons you stated here do not really answer why Java is popular. Those answers can effectively apply to any language that meets the criteria. Does meeting this criteria of popularity make it any significant over the rest?
