Java abstract class & abstract methods,Abstract class in java
Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.

The lecture was condcuted by Tushar B Kute at YCMOU, Nashik through VLC orgnanized by MSBTE. The contents can be found in book "Core Java Programming - A Practical Approach' by Laxmi Publications.
In the Java programming language, the final keyword is used in several different contexts to define an entity that can only be assigned once. Once a final variable has been assigned, it always contains the same value.
This keyword is a reference variable that refer the current object in java.
This keyword can be used for call current class constructor.

6. Constructors
The static keyword is used in Java mainly for memory management. It is used with variables, methods, blocks and nested class. It is a keyword that is used for share the same variable or method of a given class. This is used for a constant variable or a method that is the same for every instance of a class.
Static Keyword Static is a keyword in C++ used to give special chara.pdfKUNALHARCHANDANI1
Static Keyword Static is a keyword in C++ used to give special characteristics to an element.
Static elements are allocated storage only once in a program lifetime in static storage area. And
they have a scope till the program lifetime. Static Keyword can be used with following, Static
variable in functions Static Class Objects Static member Variable in class Static Methods in class
Static variables inside Functions Static variables when used inside function are initialized only
once, and then they hold there value even through function calls. These static variables are stored
on static storage area , not in stack. void counter() { static int count=0; cout << count++; } int
main(0 { for(int i=0;i<5;i++) { counter(); } } Output : 0 1 2 3 4 Let\'s se the same program\'s
output without using static variable. void counter() { int count=0; cout << count++; } int main(0
{ for(int i=0;i<5;i++) { counter(); } } Output : 0 0 0 0 0 If we do not use static keyword, the
variable count, is reinitialized everytime when counter() function is called, and gets destroyed
each time when counter() functions ends. But, if we make it static, once initialized count will
have a scope till the end of main() function and it will carry its value through function calls too.
If you don\'t initialize a static variable, they are by default initialized to zero. Static class Objects
Static keyword works in the same way for class objects too. Objects declared static are allocated
storage in static storage area, and have scope till the end of program. Static objects are also
initialized using constructors like other normal objects. Assignment to zero, on using static
keyword is only for primitive datatypes, not for user defined datatypes. class Abc { int i; public:
Abc() { i=0; cout << \"constructor\"; } ~Abc() { cout << \"destructor\"; } }; void f() { static Abc
obj; } int main() { int x=0; if(x==0) { f(); } cout << \"END\"; } Output : constructor END
destructor You must be thinking, why was destructor not called upon the end of the scope of if
condition. This is because object was static, which has scope till the program lifetime, hence
destructor for this object was called when main() exits. Static data member in class Static data
members of class are those members which are shared by all the objects. Static data member has
a single piece of storage, and is not available as separate copy with each object, like other non-
static data members. Static member variables (data members) are not initialied using constructor,
because these are not dependent on object initialization. Also, it must be initialized explicitly,
always outside the class. If not initialized, Linker will give error. class X { static int i; public:
X(){}; }; int X::i=1; int main() { X obj; cout << obj.i; // prints value of i } Once the definition for
static data member is made, user cannot redefine it. Though, arithmetic operations can be
performed on it. Static Member Functions These functions work for the .

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

6. static keyword
1. Static variable
Program of counter without static variable
Program of counter with static variable
Static method
Restrictions for static method
Why main method is static ?
Static block
Can we execute a program without main
method ?
2. The static keyword in java is used for memory
management mainly. We can apply java static
keyword with variables, methods, blocks and
nested class. The static keyword belongs to
the class than instance of the class.
3. The static can be:
◦ variable (also known as class variable)
◦ method (also known as class method)
◦ block
◦ nested class
4. If you declare any variable as static, it is
known static variable.
◦ The static variable can be used to refer the common
property of all objects (that is not unique for each
object) e.g. company name of employees,college
name of students etc.
◦ The static variable gets memory only once in class
area at the time of class loading.
5. It makes your program memory efficient (i.e
it saves memory).
6. class Student{
int rollno;
String name;
String college="ITS";
}
Suppose there are 500 students in my college,
now all instance data members will get memory
each time when object is created.All student have
its unique rollno and name so instance data
member is good.Here, college refers to the
common property of all objects.If we make it
static,this field will get memory only once.
Java static property is shared to all objects.
7. //Program of static variable
class Student8{
int rollno;
String name;
static String college ="ITS";
Student8(int r,String n){
rollno = r;
name = n;
}
void display (){System.out.println(rollno+" "+name+" "+co
llege);}
8.
public static void main(String args[]){
Student8 s1 = new Student8(111,"Karan");
Student8 s2 = new Student8(222,"Aryan");
s1.display();
s2.display();
}
}
9.
10. In this example, we have created an instance
variable named count which is incremented in
the constructor. Since instance variable gets
the memory at the time of object creation,
each object will have the copy of the instance
variable, if it is incremented, it won't reflect
to other objects. So each objects will have the
value 1 in the count variable.
11. class Counter{
int count=0;//will get memory when instance is created
Counter(){
count++;
System.out.println(count);
}
public static void main(String args[]){
Counter c1=new Counter();
Counter c2=new Counter();
Counter c3=new Counter();
}
}
12. As we have mentioned above, static variable
will get the memory only once, if any object
changes the value of the static variable, it will
retain its value.
13. class Counter2{
static int count=0;//will get memory only once and retain its value
Counter2(){
count++;
System.out.println(count);
}
public static void main(String args[]){
Counter2 c1=new Counter2();
Counter2 c2=new Counter2();
Counter2 c3=new Counter2();
}
}
14. If you apply static keyword with any method,
it is known as static method.
◦ A static method belongs to the class rather than
object of a class.
◦ A static method can be invoked without the need
for creating an instance of a class.
◦ static method can access static data member and
can change the value of it.
15. //Program of changing the common property of all objects(static field).
class Student9{
int rollno;
String name;
static String college = "ITS";
static void change(){
college = "BBDIT";
}
Student9(int r, String n){
rollno = r;
name = n;
}
17. //Program to get cube of a given number by static m
ethod
class Calculate{
static int cube(int x){
return x*x*x;
}
public static void main(String args[]){
int result=Calculate.cube(5);
System.out.println(result);
}
}
18. There are two main restrictions for the static
method. They are:
◦ 1. The static method can not use non static data
member or call non-static method directly.
◦ 2. this and super cannot be used in static context.
class A{
int a=40;//non static
public static void main(String args[]){
System.out.println(a);
}
}
19. Ans) because object is not required to call
static method if it were non-static method,
jvm create object first then call main()
method that will lead the problem of extra
memory allocation.
20. Is used to initialize the static data member.
It is executed before main method at the time
of classloading.
21. class A2{
static{System.out.println("static block is invo
ked");}
public static void main(String args[]){
System.out.println("Hello main");
}
}
Output:static block is invoked
Hello main
22. Ans) Yes, one of the way is static block but in
previous version of JDK not in JDK 1.7.
class A3{
static{
System.out.println("static block is invoked");
System.exit(0);
}
}
Output:static block is invoked (if not JDK7)
23. In JDK7 and above, output will be:
Output:Error: Main method not found in class
A3, please define the main method as: public
static void main(String[] args)
