java create array of objects with constructor
Can we create object in constructor in Java?
Constructor is just used to initialize the state of the object created.
It does not create an object itself.
An object state can also be contained in an abstract super class.
So, the purpose of invocation of Abstract class constructor, is only to initialize the object completely, and no object is created in process.An array of objects in java is created with the help of the Object class.
The Object class is kind of the root class of all the classes.
To create an array of objects, we use the class name which is followed by a square bracket([]), and then we also provide the variable name.
