JAVA waddo endoooooo

[Dhanuka Nilanjana]

Write Abstract Data Type (ADT), class implementation and Demonstration classes (Like in the sample triangle example) for the following objects:
a) Square
b) Circle
c) Student

Write the get and set methods for the above classes with appropriate parameters/arguments.

Create a separate class to demonstrate object creation and method calling for the above classes


Meke Square Circle Student kiyana tunata package hadala karanna oni kiyala kiwwa mata hariyata terumak na ema karanne komada kiyala puluwan kenek balala help ekak denna (Package eka hadala eka programme eke coding ekata import karanna onilu).

ee kiyanne squre, student, circle kiyana java classes 3 wena wenama packages wala thiyenna oni kiyana eka,ee kiwwe ee classes 3 wena wenama folders wala thiyenna oni, okkoma eke thiyenna be. Abstract common class ekak ee folder 3 ta eliyen thiyanna,
Oya code karanna use karanne IDE ekak da? ee kiwwe java code karanna puluwan application ekak da? such as eclipse, netbeans, intelij..wage ekak da? eewagen code karanawanam oya class nikamma import wenawa ctrl+shift+O gehuwama.

therenne na banz
Like in the sample triangle example me sample eka diyan..

Ehema example ekak dunne naha ban u mama hitanne uta wadiya java ba kohen hari aran tamai mekath apita karanna dunne mama search kala internet eke eth naha ban. poddak indapan mama SinhaRuba hadala ewapu coding eka metana dannam


package student;

public class Student {
private String firstName;
private String lastName;
private int age;
private String address;
public Student(String firstName, String lastName, int age, String address) {
super();
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
this.address = address;
}
public Student() {
super();
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
@Override
public String toString() {
return "Student [firstName=" + firstName + ", lastName=" + lastName
+ ", age=" + age + ", address=" + address + "]";
}


}

============================

then test class for student that outside the student package

import student.Student;
//import the student package

public class TestApplication {

public static void main(String[] args) {

//u can set values like this or
Student student = new Student("Amal","Perera",24,"Colombo");

//this

student.setFirstName("Kamal");
student.setLastName("Silva");
student.setAge(40);
student.setAddress("Matara");


System.out.println(student);
}


}

meka thamay mamath kiwwe, mekata thawa Abstract class ekak danna shape kiyala, eeka anik packages athulata danne nethuwa eliyen thiyanna. anith student, circle, squre classes me abstract class eka extend karala hadanna>
Eg : public abstract class Shape {

abstract double getArea()
{ }

abstract String getName()
{ }

}

public class Circle extends Shape{}

eewage abstract methods override karala implement karanna.
gemburu wedi da?
