The correct answer is: C. assignment
A constructor is a special method that is called when an object is created. It is used to initialize the object’s data members. The most common operation used in constructors is assignment. This is because the constructor needs to assign values to the object’s data members in order to initialize them.
The other options are not as common in constructors. Addition is used to add two numbers together. Overloading is used to create multiple versions of a method with the same name but different parameters. Polymorphism is used to create objects that can be used in different ways.
Here is an example of a constructor that uses assignment:
“`class Person {
String name;
int age;
Person(String name, int age) {
this.name = name;
this.age = age;
}
}
“`
In this example, the constructor is called when a new Person object is created. The constructor assigns the values of the name and age parameters to the object’s name and age data members, respectively.
