1. Why do we need objects in java? (2.) Why do we need methods in java? ... Thanks expecting your reply soon

Answer 1

Because it's much easier to code and keep a project organized using objects (OOP model) than a traditional procedural model. Do some research about OOP and you will understand why it is so useful and why it actually replaced the old approach to programming.

Answer 2

I will give examples here: Because it maps nicely to real objects in the real world like object person, car, house(house class I.e an architects blueprint can be used to design several house objects). These objects can then perform actions. Like walk, drive etc(We call these doing verbs, methods) . Objects like car have to be first manufactured from a factory and made available to you through a dealership(interfaces) to pick and use them and pick up another one anytime (implementing interfaces)
