To print the names of all departments in an organization using Java 8, you will need a data structure representing the departments. Assuming you have a Department class, here is an example with output:

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

public class Department {
    private String name;

    public Department(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public static void main(String[] args) {
        // Sample data
        List<Department> departments = Arrays.asList(
                new Department("HR"),
                new Department("Finance"),
                new Department("IT"),
                new Department("Marketing")
        );

        // Print the names of all departments using Java 8 streams
        departments.stream()
                .map(Department::getName)
                .forEach(System.out::println);
    }
}

Output:

Copy code
HR
Finance
IT
Marketing

In this example:

• The Department class has an attribute for the department name.
• Sample data is created in the main method with a list of Department objects.
• Java 8 streams are used to map each department to its name (Department::getName) and print the result using forEach.
