Java Class and Objects

Java is an object-oriented programming (OOP) language. It allows you to divide complex problems into smaller sets by creating objects.

These objects share two characteristics: 

• state
  
• behavior
  

Let's take few examples:

1. Laptop is an object
   • It can be in on or off state.
   • You can turn on and turn off lamp (behavior).
2. Bicycle is an object
   • It has current gear, two wheels, number of gear etc. states.
   • It has braking, accelerating, changing gears etc. behavior.
