Implementing Interfaces in Java

Interface are used as “superclasses” whose properties are inherited by classes. It is necessary to create a class that inherits the given interface.

Let have a look ,how can be this done

interface HelloWorld{  
void print();  
}  
class A implements HelloWorld{  
public void print()
{
    System.out.println("Techarge");
}  
public static void main(String args[]){  
A obj = new A();  
obj.print();  
 }  
}
