Answer:
// Create a MyClass class
public class MyClass {
int x; // Create a class attribute
// Create a class constructor for the MyClass class
public MyClass() {
x = 5; // Set the initial value for the class attribute x
}
public static void main(String[] args) {
MyClass myObj = new MyClass(); // Create an object of class MyClass (This will call the constructor)
System.out.println(myObj.x); // Print the value of x
}
}
// Outputs 5
Answer:
We define a constructor as x() ,when class name is x.
Explanation:
- Constructor in Object Oriented Programming is a special method that is invoked automatically at the time an object is created.
- It is used to initialize the data members of new objects .
- The constructor has the same name as the class.
- A Constructor is invoked at the time of object creation. It then provides data for the object . that is why it is known as constructors.
- Constructor does not return a value, so they do not have a return type also.
- Prototype of Constructors:
<class-name> (list of parameters);
- Constructors can be defined inside a class declaration or outside the class declaration.
The syntax for defining the constructor within the class is as follows:
<class-name> (list of parameters) { // constructor definition }
The syntax for defining the constructor outside the class is as follows:
<class-name>: :<class-name> (list of parameters) { // constructor
definition}
- Hence, We define a constructor as x() ,when class name is x.
