Java Interfaces Basics - ashish9342/FreeCodeCamp GitHub Wiki
But wait, my manager has given me a set of strict specifications every class to create, but has told me you can implement it in whichever way you want. Incidentally, Java has a nifty feature of Interfaces which does exactly that!
interface Car {
public String getName();
public String getManufacturerName();
}
class ElectricCar implements Car {
private String name;
private String manufacturerName;
public ElectricCar(String name, String man) {
this.name = name;
this.manufacturerName = man;
}
public void charge() {
System.out.println("Charging ...");
}
// Getter method
public String getName() {
return name;
}
// Getter method
public String getManufacturerName() {
return manufacturerName;
}
}🚀 Run Code
So interface basically binds you to a contract to follow, where you must implement all the methods. If you don't, the compiler will complain! Know more about the awesome power of Interfaces here.
