// Displaying account details
account.displayAccountDetails();
}
}

Output:

Explanation:

• In this program, we define a class BankAccount with attributes accountNumber and balance.
• We provide a default constructor for the BankAccount class, which initializes the accountNumber attribute to
a default value (“0000000000”) and the balance attribute to zero.

• In the main method, we create an instance of the BankAccount class using the default constructor.
• We call the displayAccountDetails method of the BankAccount class to display the account details.
Default constructors are invoked automatically when an object is created if no other constructor is explicitly
defined. They initialize the object’s attributes to default values, ensuring that the object is in a consistent state
upon creation. Default constructors are particularly useful when no specific initialization is required.

2 Parameterized Constructor

TASK 1: Salary details of an employee
//Salary details of an employee
class Employee {
String name;
double salary;

// Parameterized constructor
Employee(String name, double salary) {
this.name = name;
this.salary = salary;

}
// Method to display employee details
void displayDetails() {
System.out.println(“Name: “ + name);
System.out.println(“Salary: “ + salary);
}
