When you implement an interface, you're agreeing to adhere to the contract defined in the interface. That means you're agreeing to provide legal implementations for every method defined in the interface, and that anyone who knows what the interface methods look like can rest assured that they can invoke those methods on an instance of your implementing class. (Thy need not bother much about how you have implemented it. All they bother about is whether a method of the name mentioned in the interface is available or not)
Now, you might stop me and ask, what if I implement an interface and opt not to write code for a method that I am supposed to? The answer is simple. The compiler wouldn't let you do that. You cannot successfully implement an interface without providing method implementation for all the methods declared inside the interface. This is how the java system ensures that when someone knows a certain method name in an interface and has an instance of a class that implements it, can actually call that method without fear that the method isn't implemented inside the class.
Assuming an interface, Convertible, with two methods: openHood(), and setOpenHoodFactor(), the following class will compile:
public class Ball implements Convertible { // Keyword 'implements'
public void openHood() { }
public void setOpenHoodFactor(int bf) { }
}
Ok, I know what you are thinking now. "This has got to be the worst implementation class that you have seen". Though it compiles and runs as well, it is actually doing nothing… the interface contract guarantees that the class implementing it will have a method of a particular name but it never guaranteed a good implementation. In other words, the compiler does not bother whether you have code inside your method or not. All it cares is if you have methods of the matching names as in the interface. That's all…
Implementation classes must adhere to the same rules for method implementation as a class extending an abstract class. In order to be a legal implementation class, a nonabstract implementation class must do the following:
• Provide concrete (nonabstract) implementations for all methods from the declared interface.
• Follow all the rules for legal overrides.
• Declare no checked exceptions on implementation methods other than those declared by the interface method, or subclasses of those declared by the interface method.
• Maintain the signature of the interface method, and maintain the same return type (or a subtype).
• It does not have to declare the exceptions declared in the interface method declaration
Interfaces refer to programs or devices that enable a given user to communicate with the computer. It also refers to a point where two organizations and subjects interact.
You need to be more clear in what type of "interface" you are inquiring about. Linux has it's own API (Application Programming Interface) and ABI (Application Binary Interface). If you are referring to the user interface, Linux can have a GUI, a command line, or even no interface at all.
A mouse because you use it to control a cursor on your screen, the cursor is part of the graphical user interface
Which is the most common encapsulation in use on BRI Interface ? A. SDLC B. ATN C. HDLC D. PPP
Yes. An interface in essence is a java class and so you can use the term interface class. But, using the term class along with the term interface can cause ambiguity or misunderstandings among novice java developers. So, using the term "Interface" along would suffice to refer to a type of class which is the "Interface"

no you cannot use protools without an interface as a matter of fact you cant use it with just any interface either it must be a protools compatible interface and the software must be compatible with the interface.
No, bluetooth is a serial interface.
No, they use picture based interface
oh..god..i just came interface
To use this with an iPhone, you need to add the Tascam iXJ2 interface
3D interface

when the window is user friendly then we can easily use the user interface.

GUI (pronounced "gooey") = Graphical User Interface
When an interface is easy to use it is normally referred to as a user friendly interface. A friendly user interface saves time and does not require any special skills to operate.
yes of cause interface is use in java at the place of multiple inheritance .o as like multiple inheritance u can extends interface class to other. and another think is interface contain abstract method i.e method with no defination so u can use it without any error.
