The most common operation used in constructors is _____ A. addition B. overloading C. assignment D. polymorphism

addition
overloading
assignment
polymorphism

The correct answer is C. assignment.

A constructor is a special type of method that is used to initialize an object of a class. It is called when an object is created. The most common operation used in constructors is assignment. This is because the constructor needs to assign values to the object’s members.

For example, the following code shows a constructor for a class called Person:

“`class Person {
String name;
int age;

Person(String name, int age) {
this.name = name;
this.age = age;
}
}
“`

When a Person object is created, the constructor is called. The constructor assigns the values "John Doe" and

25 to the name and age members, respectively.

The other options are incorrect. Addition is not a common operation used

in constructors. Overloading is a technique that allows a class to have multiple methods with the same name but different parameters. Assignment is not a type of polymorphism.
