+You're given a file named employees.txt with employee details. Each line in the file is formatted as:
+
+EmployeeName,Age,Salary
+
+1.Create an Employee class that has:
+
+1.1 Private fields: name (String), age (int), and salary (double).
+1.2 A constructor to initialize these fields.
+1.3 Getter and Setter methods for each field.
+1.4 Add a method validateAge() in the Employee class. This method should throw an IllegalArgumentException if the age is less than 18 or more than 65.
+
+1.5 Add another method validateSalary() in the Employee class. This method should throw an IllegalArgumentException if the salary is less than 30000.
+
+2. Read the employees.txt file, and for each line:
+
+2.1 Create an Employee object.
+2.2 Use the setter methods to set the name, age, and salary. Ensure you use the validateAge() and validateSalary() methods when setting these values.
+2.3 Add the employee object to a list of employees.
+
+3. Finally, print out all the employees' names, ages, and salaries. Handle potential exceptions when reading from the file.
