Answer 1

import java.util.PriorityQueue;

import java.util.Scanner;

public class queue {

private static final int numOfNames = 4;

public static void main(String[] args) {

PriorityQueue<String> nameQueue = new PriorityQueue<>();

Scanner cin = new Scanner(System.in);

String userInput;

System.out.println("Enter " + numOfNames + " names!!\n");

for(int i = 0; i < numOfNames; ++i){

System.out.print("Name #" + (i+1) + ": ");

nameQueue.add(cin.nextLine());

}

while (nameQueue.size() > 0){

System.out.print("Press H to say Hi to each of them: ");

userInput = cin.nextLine();

if(userInput.equals("H")){

System.out.println("Hi " + nameQueue.peek());

nameQueue.remove();

}

}

}

}

The above should do the trick for this problem, if you have any other issues with Java or mostly any other language, I am available for online tutoring!
