Interface Example:
import java.io.*;
// A simple interface
interface In1
{
// public, static and final
final int a = 10;
// public and abstract
void display();
}
// A class that implements the interface.
class TestClass implements In1
{
// Implementing the capabilities of
// interface.
public void display()
{
System.out.println("This is the awesome course");
}
// Driver Code
public static void main (String[] args)
{
TestClass t = new TestClass();
t.display();
System.out.println(a);
