A class teacher wants to arrange the names of her students in alphabetical order. Define a class NameSorter that stores the given names in a one-dimensional array. Sort the names in alphabetical order using Bubble Sort technique only and display the sorted names.
Aryan, Zoya, Ishaan, Neha, Rohan, Tanya, Manav, Simran, Kabir, Pooja

public class NameSorter
{
    void bubbleSort(String names[]) {
        int len = names.length;
        _______(1)_________ {
            _______(2)_________ {
                _______(3)_________ {
                    String t = names[j];
                    _______(4)_________
                    _______(5)_________
                }
            }
        }
    }
    
    public static void main(String[] args) {
        
        String arr[] = {"Aryan", "Zoya", 
                        "Ishaan", "Neha", 
                        "Rohan", "Tanya",

        NameSorter obj = new NameSorter();
        obj.bubbleSort(arr);
        
        for (int i = 0; i < arr.length; i++) {
            System.out.println(arr[i]);
