Master Java Interfaces #programming #javaforbeginners #javaexperts #javaclass #interface #spcoaching

"In Java, an interface is like a contract. It defines what a class should do, but not how it does it! 🎯"

📌 Key Points:
✔ Interfaces only have method declarations (no body) 📝
✔ A class implements an interface using implements 🔄
✔ Supports multiple inheritance (unlike classes) 🔗

Example:
// Interface definition
interface Vehicle {
void start(); // Abstract method (no body)
}

// Class implementing the interface
class Car implements Vehicle {
public void start() {
}
}

public class InterfaceExample {
public static void main(String[] args) {
Vehicle myCar = new Car(); // Interface reference
}
}
