Object Oriented Programming

Instantiation in Java

Instantiation is used to create an object instance from a class (instantiate).

className objectName = new className(inputParameters);


Input requirements are taken from the constructor. A class can have multiple constructors with different numbers of input parameters and types, to create different objects.

An instance of a class is called an object.

//class looks like this
public class Car {
    String make;
    public Car(string make) {
        this.make = make;

//instantiation, elsewhere in the program
Car myCar = new Car("Honda"); //passing in Honda into the make variable
