example of interface
Example 1: interface in java
public class MammalInt implements Animal {
public void eat() {
System.out.println("Mammal eats");
}
public void travel() {
System.out.println("Mammal travels");
}
public int noOfLegs() {
return 0;
}
public static void main(String args[]) {
MammalInt m = new MammalInt();
m.eat();
m.travel();
}
}
Example 2: what is interface
Interfaces specify what a class must do.
It is the blueprint of the class.
It is used to achieve total abstraction.
We are using implements keyword for interface.
Basic statement we all know in Selenium is
WebDriver driver = new FirefoxDriver();
WebDriver itself is an Interface.
So we are initializing Firefox browser
using Selenium WebDriver.
It means we are creating a reference variable
of the interface and creating an Object.
So WebDriver is an Interface and
FirefoxDriver is a class.
Example 3: interface in java
interface Animal {
public void eat();
public void travel();
}
