Class Objects
An object of a class can be created using the following syntax:
index
We can access the field of a class using the dot (.
) operator:
index
For-example:
index
The expression new Player();
is used for creating a new object while Player p1
is used for creating a variable for storing that new object. So simply writing Player p1;
will only create an empty variable with no object inside it therefore we have to create a new object and, in turn, store it into a variable: Player p1 = new Player();
.
Therefore, if we create an Array of size 10
using the Player
class, it won't create 10 objects, rather, it will create an empty array with a capacity to store 10 Player objects. This can be understood by the following example:
index
The error says "Object reference not set to an instance of an object" which simply means that we are trying to access data from an object that is not there - there is no object to access at the index 0
.
This can be fixed by manually creating an object at the index 0
:
index
