Q.Write a java program to accept n employee names from user. Sort them in ascending order and Display them.(Use array of object and Static keyword)[25 M]

import java.util.Scanner;

class Employee {
    String name;

    // Constructor
    Employee(String name) {
        this.name = name;

        for (int i = 0; i < n - 1; i++) {
            for (int j = i + 1; j < n; j++) {
                // Compare names and swap
                if (emp[i].name.compareToIgnoreCase(emp[j].name) > 0) {
                    Employee temp = emp[i];
                    emp[i] = emp[j];
                    emp[j] = temp;
                }
            }
        }
    }

    // Static method to display employees
    static void displayEmployees(Employee[] emp) {
        System.out.println("\nEmployee Names in Ascending Order:");
        for (Employee e : emp) {
            System.out.println(e.name);
        }
    }
}

public class EmployeeSort {
    public static void main(String[] args) {

        System.out.print("Enter number of employees: ");
        int n = sc.nextInt();
        sc.nextLine(); // consume newline

        // Array of objects
        Employee[] emp = new Employee[n];

        // Accept names
        for (int i = 0; i < n; i++) {
            System.out.print("Enter employee name " + (i + 1) + ": ");
            String name = sc.nextLine();
            emp[i] = new Employee(name);
        }

        // Sort using static method
        Employee.sortEmployees(emp);

        // Display using static method
        Employee.displayEmployees(emp);

        sc.close();
