Why is the new keyword used only for object creation and not for variables in Java?

• The new keyword in Java is used to create an object of a class in heap memory.
• It allocates memory for all instance variables and initializes them using the constructor.
• Static variables belong to the class and are created when the class is loaded, so they do not need new.
• Variables like int, String, or class fields are not objects by themselves and cannot be created using new.
• Therefore, new is required only to create objects, not to access or declare variables.

Example:

public class Supermarket
{
    static String shopName="arul";
    static int shopNo=3;
    String productName="eye";
    int productNo=1;
public static void main (String[] args)
{
    Supermarket product=new Supermarket();

    System.out.println(product.shopName);
    System.out.println(product.shopNo);
    System.out.println(product.productName);
    System.out.println(product.productNo);
}
}

How to read this image :

Stack
Holds reference variables like product
→ Supermarket product

Heap
Holds the actual object created by
→ new Supermarket()

Static variables
(shopName, shopNo)
→ Stored once in class memory, NOT inside the object

Instance variables
(productName, productNo)
→ Stored inside the heap object
