How can I call a constructor for creating an instance of a particular class?

73    Asked by Deepalisingh in Salesforce , Asked on Feb 7, 2024

There is a scenario where I have a class whose name is “car”. This particular class has parameterized constructor. How can I call this particular constructor to create an instance of the class “car” and even initialize its properties?

In the context of Salesforce, you can call a particular constructor for creating an instance if you have a class whose name is “car” with a parameterized, by using the following example which is a coding analogy written in a programming language such as Java programming language:-

Public class Car {
    Private String model;
    Private int year;
    // Parameterized constructor
    Public Car(String model, int year) {
        This.model = model;
        This.year = year;
    }
    Public static void main(String[] args) {
        // Calling the constructor to create an instance of the Car class
        Car myCar = new Car(“Toyota”, 2022);
        // Now myCar has been initialized with the specified model and year
    }
}

In this above example, the class of “car” has a parameterized constructor which would take a mode1 (string) and a “year”( int). The “main” method would demonstrate how can you call this particular constructor for creating a “car” object with the specific values for mode1 and year.
