Welcome To Tips Arena

Hello guys humne apni peechli post main Java Control Statements ke bare main pda tha or ab hum seekhenge Java Classes ke bare main to chaliye friends hum seedhe topic pe aate hain.


Java Classes Introduction In Hindi
Friends hum sabse pehle baat karenge java classes ke bare main dosto java main class ko hi sab kuch mana jata hai, dosto class type hota hai hum class type ke bhi variable create karte hain inme difference bas itna hota hai ki class type variables objects kehlate hain, dosto class ke through hum bahut se variables or functions ka group structure create karte hain or unhe ek name se identify karte hain dosto is structure ke base par kayi object create kiye ja sakte hain.

Friends class ek entity or usse judi attributes ko reflect karti hai agar bina class ke hum kisi person ke bare main information store kare ya represent kare to iske liye hume kayi variables ki aawasyakta hogi, for example name, age, address, phone number etc.. for example 500 person's ke bare main information store karni hai esi situation main hume 500*4=2000 variables create karne padenge, dosto isme time or hard work bahut jada lagega, friends is problem se bachne ke liye classes ko introduce kiya gya hai, friends classes ke through hum in 4 variables ka type create kar sakte hain or fir us type ke 500 objects create kar sakte hain, friends fir hum object ke through class ke har variable ko access karke value assign kar sakte hain for example è

class People

{

    String name;

    int age;

    int phone;

    String address;

}

Dosto ek program main kitni bhi classes create ki ja sakti hain lekin dosto main method sirf ek hi class main hoga, dosto main method se hi program ka execution start hota hai.

Advantages Of Classes In Hindi

Friends hum aapko sabse pehle classes ke kya kya advantages hote hain iske bare main batayenge.

Security

Friends humare variables or methods classes main hote hain friends classes hume 3 level ka access protection provide karti hai, friends jab tak hum khud na chahe tab tak koi bhi humare class members ko access nhi kar sakta hai.

Reduce complexity

Friends classes ka use karne se hum variables or methods ke merge hone se bach jate hain, dosto classes se humare program simple ban jata hai or fir uski complexity dur ho jati hai.

Separation

Friends kisi bhi program main humare paas kayi types ka data hota hai, friends different different data par different different operations perform kiye jate hain jo method ke through hi perform hote hain, dosto jab hum classes ka use karenge to hum ek type ke data or usse related operations 'methods' ko dusre type ke data or usse related operations 'methods' se separate kar sakte hain.

Dosto hum esa har trah ke data ke liye alag se class banakar kar sakte hain, dosto us data par perform hone wale operations bhi hum usi class main create kar sakte hain, dosot isse humara program ko manage karne easy ho jata hai, for example hum ek class banaye or purchase ke bare main information store karne ke liye or dusri class sales ki information store karne ke liye bana sakte hain.

Focus On Data

Friends jab hum classes use karte hain to program ka pura focus data par hota hai, friends hum data ke liye hi methods create karte hain or data ko hi hide karte hain, friends classes data focused approach hai jo ki useful software banane ke liye bahut hi important hai.

Creating A Class

Friends humare liye class ko create karna bahut hi simple hai dosto iske liye hume class keyword ka use karna hota hai, class keyword ke baad class ka name diya jata hai or dosto agar hum program main ek se jada classes ka name unique nhi rakhenge to hume problem ho sakti hai isliye friends humesa classes ka name unique hi rakhe, dosto jis class me main method hota hai vo class public declare ki jani chahiye, friends aayiye jane ki class ko kese create kiya jata hai è

class People

{

    String Name = "Manoj";

    int age = 23;

    Public void display()

    {

        System.out.println("Name is"+Name+"Age is"+age);

     }

     public static void main(String args[])

     {

          this.display();

     }

}

Friends humne jo uper example diya hua hai usme people name ki ek class create ki hai, dosto is class main name or age 2 variables hain, friends isme display() name se method bhi declare kiya gya hai. dosto Main method me display() method ko call kiya gya hai.

Main Method In Hindi

Friends ab hum main method ke bare main study karenge dosto hum aapko bta de ki humare program main classes to ek se jada ho sakti hain par main method sirf ek hi hota hai, dosto pure program main jaha main method hota hai wahi se program execution start hota hai jis class me main method hota hai use public declare karna necessary hota hai.

Friends hum aapko bta de ki main method ko bhi humesa public declare kiya jana chahiye dosto hume esa karna isliye bhi jaruri hai kyunki classes main sare methods by default private hote hain or agar main method ko public declare nahi kiya jaye to java run time environment humare main method ko access nahi kar payega or humare program ka execution start nahi hoga.

Friends jesa ki hum sabhi jante hain ki class ke kisi bhi method ko access karne ke liye objects ki jarurat hoti hai, dosto java run time environment humare main method ko bina object ke access kar sake isliye main method ko static bhi declare kiya jata hai.

Friends ab hum aapko necessary terms ke bare main batayenge è

Instance Variable (Methods) In Hindi

Friends instance variable ya method unko kaha jata hai jo variables or methods class ke object se hi access kiye jate hain.

Static Variables (Methods) In Hindi

Friends static variables or methods ko bina objects ke access kiya ja sakta hai dosto kisi bhi variable ya method ko static banane ke liye static keyword use kiya jata hai static members ko access karne ke liye class ke name ke aage (.) operator lga kar us member ka name likha jata hai.

Command Line Argument In Hindi

Friends main method ke parameters ke roop main string array hota hai, dosto aisa command line argument dene ke liye kiya gya hai command line arguments vo arguments hote hain jo hum program ko run karte time hi de sakte hain dosto bahut bar esa hota hai ki hum program run hote time hi kuch argument dena chahte hain taki humara program un arguments ke according run ho sake.

Final Words

To dosto ye thi humari aaj ki post jisme hume Java Classes ke bare main seekha dosto hume ummid hai ki aapko humari ye post pasand aayi hogi or hum aasha karte hain ki aap humari is post ko share jarur kare or comment box main comment karna bilkul na bhoole Thanks..
