what are interfaces used for java code example
Example 1: interface in java
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 2: java interface
public interface Exampleinterface {
public void menthod1();
public int method2();
}
class ExampleInterfaceImpl implements ExampleInterface {
public void method1()
{
}
public int method2()
{
}
}
