Dependency Inversion Principles (DIP)

Comment

The Dependency Inversion Principle (DIP) states that high level modules should not depend on low level modules; both should depend on abstractions.

Abstractions should not depend on details. Details should depend upon abstractions

public class Store {
    PaymentGateway paymentGateway;
    class Store() {
    }
    public void setPaymentGateway(PaymentGateway pg) {
        this.paymentGateway = pg;
    }
    public void sellItem() {
         this.paymentGateway.processpayment();
    }
}
class Stripe() implements PaymentGateway {
    public void processpayment() {
        System.out.println(“Earned $10 through Stripe”);
    }
}
class Paypal() implements PaymentGateway {
    public void processpayment() {
        System.out.println(“Earned $10 through Paypal”);
    }
}
interface PaymentGateway {
    public void processpayment();
}
