What is Swing in Java?- tccicomputercoaching.com

Swing is a set of program components for Java programmers that provide the ability
to create graphical user interface (GUI) components, such as buttons and scroll bars that are independent of the windowing system for specific operating system.

Swing-java-tcci

We use Java Swing for our GUI development. It’s a lot more powerful than the original AWT, and the price is right. In particular, we try to use the “Bean format” of setting and getting members, call-backs to notify of changes, etc, to make it easier to build applications from JMRI components.

TCCI teach Core Java, Advance Java, and JavaFX to Engineering student , IT Professional and any Person in Bopal and Satellite in Ahmedabad.

What is method overriding in Java? – tccicomputercoaching.com

When method of child class redefines the method of parent class then it is called method overriding in Java.

method-overriding-in-Java_simple

Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class. In this case the method in parent class is called overridden method and the method in child class is called overriding method.

A method can only be written in Subclass not in same class. The argument list should be exactly the same as that of the overridden method. The return type should be the same or a sub type of the return type declared in the original overridden method in the super class. A method declared final cannot be overridden.

Example:

1. class Human

2. { public void eat()

3. { System.out.println(“Human is eating”); }}

4. class Boy extends Human

5. { public void eat()

6. { System.out.println(“Boy is eating”); }

7. public static void main( String args[])

8. { Boy obj = new Boy(); obj.eat(); }}

What is Abstract class and abstract Method in Java -tccicomputercoaching.com


Abstract
means something, which is in thoughts but not it exists in reality. It is like that we know that what should be done, but we don’t know how it would be done.

Take an example, there is a ‘Shape’ class which contains a method ‘area()’ but we cannot implement area() method here as we do not know what will be the shape(a square, a rectangle, a triangle or any other shape) in future. In that case, we will declare area() in the Shape class and will implement the same method in our subclasses as per the requirement.

Abstract class & Method in Java_simple

Example:

1. public abstract class Shape

2. {

3.       public abstract void area(int var); // Abstract method

4. }

6. public class Circle extends Shape

7. {

8.      int radius;

9.      double pi=3.14;

10.    public void area(int var)

11.      {

12.         radius=var;

13.         System.out.println(“Arear of Circle: “+(pi*radius*radius));

14.       }

15.   }

16. public class Square extends Shape

17.  {

18.    int side;

19.    public void area(int var)

20.      {

21.         side=var;

22.         System.out.println(“Area of Square: “+side*side);

23.      }

24. }

25. public class Result

26. {

27.       public static void main(String[] args)

28.         {

29.             Shape obj=new Square();

30.             obj.area(4);

32.             Shape obj1=new Circle();

33.             obj1.area(3);

34.          }

35. }

In JAVA, Abstraction can be achieved using the abstract class, abstract methods, and interface. Using the abstract class we can achieve the different level of abstraction, but using the interfaces we can achieve 100% abstraction.

Abstract Class:

1. An abstract class would be declared using ‘abstract’ keyword.

2. Creation of object is not possible of an abstract class.

3. It may contain data members, methods, abstract methods, constructors.

4. Data members can’t be abstract.

5. It must be inherited by the subclass(es) using ‘extends’ keyword.

6. The subclass should implement each and every abstract method declared in Super Class. Otherwise, subclass would act like abstract class which needs to be extended further.

Abstract Method:

1. An abstract method can be placed within an abstract Class only.

2. It would be declared using ‘abstract’

3. The abstract method should be declared only without any implementation

4. It can be implemented only in the subclass(concrete class) using ‘extends’ or ‘implements’.

How Does Python Handle Memory Management? tccicomputercoaching.com

Python uses private heaps to maintain its memory. So the heap holds all the Python objects and the data structures. This area is only accessible to the Python interpreter; programmers can’t use it.

And it’s the Python memory manager that handles the Private heap. It does the required allocation of the memory for Python objects.

Python-Handle-Memory-Mana_simple

 

Python employs a built-in garbage collector, which salvages all the unused memory and offloads it to the heap space.

Python is most popular Language in present time.
