Your java playlist is one of the best java tutorial in youtube

Unga voice super aa iruku 😍😍 also explaining slang also just awesome 😎

Please add all the codes in description, it will be easy for us to revise before the interview day

Thanks Mam. Best Explanation 👍

Vera level ka🤩spr a purithu

thank you so much.....your explanation is very clear for all the topics.

14:20 define panniye aganum nu nammala thitudhuuu.....👍🤣🤣😝😝🤣🤣ultimate nga

You make it easy...Thank you Mam.

நன்றி அக்கா 🙏

Super 👍

Hats off !

Hi cute explanation And sweet voice

12:11 line 5 la abstract void ah //committed pannirunga abstract ah remove pannitu verum void method kodukalamay.??

Mam member class ku array objects create panum pothu new Member [ ]; nu podurom. New keyword abstract class ku use panna kudathu sonnigalay mam. elements kaana index references create pandrathunala athu allow pannuthaanga maa New Member( ); Ipdi podum pothu heap la oru object create pandrathunaala allow pannaliya mam. Correct taanu sollunga mam

package Absract; abstract class Shape { abstract void area(int n); } class Square extends Shape { void area(int n) { System.out.println("Square:" + (n * 4)); } } class Triangle extends Shape { void area(int n) { System.out.println("Triangle:" + (n * 3)); } } public class Exercise { public static void main(String[] args) { Shape[] s = new Shape[2]; s[0] = new Square(); s[1] = new Triangle(); for(Shape s1: s) { s1.area(4); } } }

Great explanation

niceeee

Mam..neenga last ah kudukura programs ku ans enga iruku??

Nice voice slang

Thank you 🙂👍

Mam, I have an one doubt? What's the difference between ( Member m1 = new Student(); and Student s1 = new Student(); ) in the time of object initialization?

I wanna ur example code !

Solution for the exercise:::: ----------------------------------------------------------------- import java.util.*; abstract class Common{ int length,breadth; abstract int area(); } class Square extends Common{ int length; Square(int length){ this.length=length; } int area(){ return length*4; } } class Triangle extends Common{ int length,breadth,height; Triangle(int length,int breadth,int height){ this.length=length; this.breadth=breadth; this.height=height; } int area(){ int a=breadth*height; return a/2; } } public class Main { public static void main(String[] args) { ArrayListc = new ArrayList(); c.add(new Square(4)); c.add(new Triangle(2,4,4)); for(Common i:c){ System.out.println(i.area()); } } }

Mam can you please add the code in the description or in the pinned comments so that we can revise easily before exam??

Accessor and mutator method sollunga

Mam Your Teaching is Very easy to learn ....Please do the playlist for DBMS and SQL

✌✌

So basically idhu inheritance dhane?

Akka ipo abstract cls ku Object create panna mudiyathuna athula iruka concrete method na epdi call panrathu....

Mam first u said for abstract u can't create object but after very mins u create array object for abstraction mam.so my question if array means i create for abstraction?? confuse mam

mam can you saggest some best book in c++ and java

Answer for the Question // Shape public abstract class Shape { abstract void area(); } class Square extends Shape { private double side ; public Square(double side){ this.side = side; } @Override void area(){ double squareArea = side*side ; System.out.println("Area of Square ="+squareArea); } } class Triangle extends Shape { private double height ; private double base; public Triangle(double height,double base){ this.height = height; this.base = base; } @Override void area() { double triangleArea = 0.5 * base * height; System.out.println("Area of Triangle ="+triangleArea); } } //Main class public class Main { public static void main(String[] args) { Square square = new Square(23); Triangle triangle = new Triangle(20,10); // triangle.area(); // square.area(); Shape[] area = new Shape[3]; area[0]= new Square(10); area[1]= new Triangle(20,10); area[2]= new Square(30); for (int i = 0; i < area.length ; i++) { area[i].area(); } } }
