Interface in java By Dheeraj Kumar Singhdheeraj_cse
In Java,
An interface is a way through which unrelated objects use to interact with one another.
Using interface, you can specify what a class must do, but not how it does it.
It is not a class but a set of requirements for classes that implement the interface.

An interface is a reference type in Java. It is similar to the class. It is a collection of abstract methods. A class implements an interface, thereby inheriting the abstract methods of the interface. Along with abstract methods, an interface may also contain constants, default methods, static methods, and nested types.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
2. Multiple inheritance means creating a new class that inherits
behavior directly from more than one superclass.
Java does not support multiple inheritance reason is
ambiguity around Diamond problem, consider a class A
has show() method and then B and C derived from A and has
there own show() implementation and now class D derive
from B and C using multiple inheritance and if we refer
just show() compiler will not be able to decide which show() it
should invoke. This is also called Diamond problem because
structure on this inheritance scenario is similar to 4 edge
diamond.
4. 4
Interface is Like a class but only contains abstract method and
final variables
example:
interface Operation{
void Add(int a,intnt b);
int Sub(int a,int b);
}
abstract interface Operation{
public abstract sub();
public abstract int sub();
}
Both are correct!
the abstract and public
keywords are implied,
so the shorthand is
recommended.
5. 5
An interface is very much like a class-with one important
difference. None of the methods declared in an
interface are implemented in the interface itself. Instead, these
methods must be implemented in any class that uses the
interface.
In short, interfaces describe behaviors but do not detail how
those behaviors will be carried out.
We save the interface's source code in a file with the .java
extension. Then use the Java compiler, javac, to compile the
source code into byte-code form. Just like a normal class, the
byte-code file will have the .class extension.
6. 6
Difference between class and interface
we cannot instantiate an interface.
An interface does not contain any constructors.
All of the methods in an interface are abstract.
An interface is not extended by a class; it is implemented by
a class.
An interface can extend multiple interfaces.
7. 7
interface student
{
public void add();
public void display();
}
For defining interface use interface keyword followed by
interface name as shown above.
When any class implements the interface then, class must be
write the definition of all methods in the interface.
8. 8
class A implements student
{
String nm;
public void add()
{ Scanner sc=new Scanner(System.in);
nm=sc.nextLine();
}
public void display()
{
System.out.print("Student name="+nm);
}
}
9. 9
Extending interface
An interface can extend another interface, similarly to the way
that a class can extend another class.
The extends keyword is used to extend an interface, and the
child interface inherits the methods of the parent interface.
11. 11
Using an Interface as a Type
When you define a new interface, you are defining a new
reference data type. You can use interface names anywhere
you can use any other data type name.
If you define a reference variable whose type is an interface,
any object you assign to it must be an instance of a class that
implements the interface.
As an example,method for finding the largest object in a pair
of objects, for any objects that are instantiated from a class
that implements Relatable
12. 12
public Object findLargest(Object object1, Object object2)
{
Relatable obj1 = (Relatable)object1;
Relatable obj2 = (Relatable)object2;
if ((obj1).isLargerThan(obj2) > 0)
return object1;
else
return object2;
}
By casting object1 to a Relatable type, it can invoke
the isLargerThan method
13. 13
Evolving Interfaces
Consider an interface that we have developed called operation:
public interface opertion
{
void Add(int i, int j);
void Mul(int a,int b);
}
Suppose later we want to add a new method so now interface
will be
public interface opertion
{
void Add(int i, int j);
void Mul(int a, int b);
void Sub(int c, int d);
}
14. 14
If we make this change, then all classes that implement the
old operation interface will break because they no longer
implement the old interface.
If you want to add additional methods to an interface, you
have several options. Create oprationplus interface that
extends operation:
public interface operationplus extends operation
{
void sub(int c, int d);
}
15. 15
Default methods
Alternatively, we can define your new methods as default
methods. The following example defines a default method
named sub:
public interface opertion
{
void Add(int i, int j);
void Mul(int a, int b);
default void Sub(int c, int d){//method body}
}
Note that we must provide an implementation for default
methods
