Java Class Attributes In Hindi
Contents
Jo Ham Variable Ke Sath x And Any Variable Name Create Karte Hai, To Ham Use Hi Attributes Kahte Hai, Or Agar Attributes Ko Class Ke Under Create Kiya Jata Hai, To Ham Use Class Attributes Kahte Hai, Iska Example Aap Niche Dekh Sakte Hai |
Example:
public class MyAttributes{
int x = 10; // class attributes
int y = 20 ; // class attributes
}Java Accessing Attributes In Hindi
Java Me Jab Attributes Create Jate Hai, To Aap Unhe Access Bhi kar Sakte Hai, Java Me Attributes Access Karne Ke Liye (.) Dot Operator Ka Istemal Karte Hai |
Example:
public class MyAttributes{
int x = 10; // class attributes
int y = 20; // class attributes
public static void main(String[] args){
MyAttributes myobj = new MyAttributes();
System.out.println(myobj.x);
System.out.println(myobj.y);
}
}Output:
10 20
Java Modify Attributes In Hindi
Aap Attributes Ko Modify Bhi Kar Sakte Hai, Modify Karne Ke Liye Aapko Pahle Attributes Access Karna Hoga And Uske Bad Aap Uski Value Ko Modify Kar Sakte Hai |
Example:
public class MyAttributes{
final int x = 10; // class attributes
public static void main(String[] args){
MyAttributes myobj = new MyAttributes();
myobj.x = 20; // will generate an error: cannot assign a value to a final variable
System.out.println(myobj.x);
}
}Output:
20
Example 2:
Agar Aapko Value Ko Modify Nhi Karna Hai, Keval Aapko Same Value Rakhni Hai, To Aap Java Me final keyword se Variable Ko Create Kar Sakte Hai, Isse Aapko Value Change Nhi Hogi And Agar Change Karne Ke Koshish Bhi ki Jati Hai, To ye Error Show Karega |
public class MyAttributes{
final int x = 10; // class attributes
public static void main(String[] args){
MyAttributes myobj = new MyAttributes();
myobj.x = 20; // will generate an error: cannot assign a value to a final variable
System.out.println(myobj.x);
}
}Output:
MyAttributes.java:6: error: cannot assign a value to final variable x
myobj.x = 20; // will generate an error: cannot assign a value to a final variable
