What is an Object and how do you allocate memory to it.

Question

Aryan Kumar · Answer

In programming, an object is an instance of a class. A class is a blueprint or template that defines the properties and methods that objects of that class will have. When you create an object, you are creating an instance of the class, which has its own set of properties and can invoke its own methods.
In order to allocate memory to an object, you need to create an instance of the class. This can be done using the
new operator in most object-oriented programming languages.
Here is an example of how to create an object in Java:
public class Person {
 String name;
 int age;
 public Person(String name, int age) {
 this.name = name;
 this.age = age;
 }
}
// create a new Person object
Person person = new Person("Alice", 25);
In this example, the Person class defines two properties, 
name and age, and a constructor that takes two parameters,
name and age, and initializes the object's properties with these values. To create a new
Person object, we use the new operator to allocate memory for the object and call the
Person constructor to initialize the object's properties with the values "Alice" and 25.
When the new operator is used to create an object, it allocates memory for the object on the heap, which is a region of memory that is managed by the programming language runtime. The object's properties are then initialized with the values specified in the constructor, and the object is ready to be used in the program.
