To find the details of the highest-paid employee in the organization using Java 8, you would need to have an additional attribute in the Employee class for the salary. Here is an example:

javaCopy code
import java.util.Arrays;
import java.util.Comparator;
import java.util.List;
import java.util.Optional;

public class Employee {
    private String name;
    private double salary;

    public Employee(String name, double salary) {
        this.name = name;
        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public double getSalary() {
        return salary;
    }

    public static void main(String[] args) {
        // Sample data
        List<Employee> employees = Arrays.asList(
                new Employee("John", 50000),
                new Employee("Jane", 60000),
                new Employee("Bob", 75000),
                new Employee("Alice", 70000),
                new Employee("Charlie", 80000)
        );

        // Find the details of the highest-paid employee using Java 8 streams
        Optional<Employee> highestPaidEmployee = employees.stream()
                .max(Comparator.comparingDouble(Employee::getSalary));

        // Output the result
        highestPaidEmployee.ifPresent(employee ->
                System.out.println("Details of the highest-paid employee:
" +
                        "Name: " + employee.getName() + "
" +
                        "Salary: " + employee.getSalary()));
    }
}

Output:

yamlCopy code
Details of the highest-paid employee:
Name: Charlie
Salary: 80000.0

In this example:

• The Employee class is modified to include a salary attribute.
• Java 8 streams are used with the max operator and a comparator to find the highest-paid employee based on their salary.
• The result is wrapped in an Optional to handle the case where the list of employees might be empty.
• The details of the highest-paid employee are then printed to the console.
