Explanation:

1 Employee Class Definition
• The program begins by defining a class named Employee.
• This class encapsulates attributes such as name and salary.
• It also includes a method named raiseSalary designed to increase an employee’s salary by a specified
percentage.
2 Create Employee Object and Print Current Salary
• Within the main method, an instance of the Employee class is created and named emp.
• The program prints the current salary of the employee (emp) to the console.

3 Method to Raise Employee Salary
• A method named raiseEmployeeSalary is introduced.
• This method takes an Employee object and a percentage as parameters.
• Internally, it calls the raiseSalary method of the Employee object, leading to an increase in the salary.
4 Raise Employee Salary in Main Method

• The raiseEmployeeSalary method is invoked within the main method, aiming to raise the salary of the
employee (emp) by 10%.
5 Print Updated Salary

• Subsequently, the program prints the updated salary of the employee (emp) to reflect the changes made
by the raiseEmployeeSalary method.
6 Conclusion

• This program serves as a practical example of how to pass objects, specifically instances of the Employee
class, to methods in Java.
• The design of the Employee class, along with the use of methods, illustrates the principles of object-
oriented programming (OOP), encapsulation, and the effective modification of object states.
This explanation aims to provide a conceptual understanding of the program without delving into the specific
code details. If you have further questions or need clarification on any specific aspect, feel free to ask!
