Object Oriented Programming in Java

vindhya Hegde — Tue, 21 Sep 2021 14:55:25 +0000

Object-oriented programming helps us with data security, code reusability, and also helps us to improve code readability.
Let us see and Understand different Object-oriented concepts with code examples.

1.Abstraction

->Means showing only essential parts and hiding the implementation details.
->Only the functionality will be provided to the user,
in other words user will have the information on what the object
does instead how it does.
->Here we will be hiding the details of our class from the outside world.What happens within the class will not be known to the outside users.

abstract class Car
{
    abstract void run();
}
class Baleno extends Car
{
    void run()
    {
        System.out.println("drive car safely");
    }
}
public class Main
{

    public static void main(String args[])
    {
       Car c = new Baleno();
       c.run();

    }

}

2.Encapsulation

->Binding variables and methods under a single entity.
->Or It is a mechanism of wrapping the data(variables) and code acting on the data(methods) together in a single unit. Data (variables) present inside class can be accessed only through methods of the current class.Therefore it is also known as data hiding,
To achieve encapsulation in java
->Declare the variables as private : if we declare variables as private then it will not be visible to the outside world.
-> If we want to access these private variables then,
Provide public setter and getter methods to modify and view the variables values.

class Student
{

    private String sname;

    public String getName()
    {
        return sname;
    }

    public void setName(String name)
    {
        sname = name;
    }

}

public class Main
{

    public static void main(String args[])
    {
        Student f1 = new Student();
        f1.setName("Vindhya");
        System.out.println(f1.getName());

    }

}

3.Inheritence

->Acquiring properties of one class to another class.
->If we consider parent class and child class ,then child class
will acquire the Properties of Parent class.
->Parent class is also known as Base class and Super class.
Child class is also known as derived class and subclass.
->In general children will acquire the properties of their parent
that is example for inheritance

class Base
{
   void method1()
   {
       System.out.println("Parent class");
   }   

}
class Derived extends Base
{
    void method2()
    {
        System.out.println("Child class");
    }
}
public class Main{
    public static void main(String args[])
    {
         Derived d = new Derived();
         d.method1();
         d.method2();
    }

}

4.Polymorphism

->The ability of an Object to take many forms
->Performing the same task in different ways.
->here task means method.Polymorphism is a combination of two
different words poly means many and morphs means forms.
->Finally polymorphism gives the meaning of many forms

class Multiply{
    static int multiply(int a,int b)
    {
        return a*b;
    }
    static double multiply(double a, double b)
    {
        return a*b;
    }
}

public class Main{

    public static void main(String args[])
    {
        System.out.println(Multiply.multiply(2,3));
        System.out.println(Multiply.multiply(1.1,2.1));

    }

}

Most Frequently asked Coding Questions

vindhya Hegde — Tue, 21 Sep 2021 10:20:29 +0000

Here I will be mainly focusing on OnCampus technical Interviews because I have attended a couple of them. and I observed these are common questions to check you know the basics of coding or not.

1.To swap two numbers without using an extra variable

import java.util.*;
public class Main
{
    public static void main(String[] args)
    {
         int a,b;
         System.out.println("Enter two numbers");
         Scanner sc = new Scanner(System.in);
         a = sc.nextInt();
         b = sc.nextInt();
         //logic to swap without using extra variable.
         a = a+b;
         b = a - b;
         a = a - b;
         System.out.println("After swapping: "+ "a="+ a +"," + "b="+ b );
    }
}

2.Check given number is Amstrong Number or not

To Know more about Amstrong Number refer the link here

import java. util.*;
public class Main
{
    public static void main(String[] args)
    {
         int a;
          Scanner sc = new Scanner(System.in);
         System.out.println("Enter the number");
         a = sc.nextInt();
         //to find length or number of digits in number
         int num = a;
         int len = 0;
         int rem;
         while(num!=0)
         {
             rem = num%10;
             num = num/10;
             len++;
         }
        //logic to check Armstrong number or Not 

        int sum = 0;
        num = a;
        while(num!=0)
        {
           rem = num%10;
           int mul= 1;
           for(int i=0;i<len;i++)
           {
               mul = mul * rem;
           }
           sum +=mul;
           num= num/10;
        }
        if(sum==a)
        {
            System.out.println("Amstrong Number");
        }
        else{

        int n1 = 0 , n2 = 1;
        int res = 0;
        for(int i=2;i<=n;i++)
        {
            res = n1+n2;
            n1 = n2;
            n2 = res;
        }
        System.out.println("Fib of n is " + res);

    }
}

        int n1 = 0 , n2 = 1;
        int res = 0;
        System.out.print("Fibonacci series is " + n1 + " " + n2 + " ");
        for(int i=2;i<=n;i++)
        {
            res = n1+n2;
            n1 = n2;
            n2 = res;
            System.out.print(res + " ");
        }


    }
}
