Storing an ArrayList Create a Java program that will store 10 student objects in an ArrayList, ArrayList. A student object consists of the following fields: int rollno String name String address Implement two comparator classes to sort student objects by name and by rollno (roll number). Implement your own selection sort method and place your code in a separate Java source file. Do not use a sort method from the Java collections library. ***Code from previous question does not work***

Write a python hangman program Modify your program so that the following functionality is added:1. Instead of selecting the word from a hard coded list, incorporate problem2 so that thelist is read from a file, then a word is randomly selected from this list.2. when the game ends, the following information should be outputted to a new file:● the word● the state of the hangman● if the user won or lostExample outputs:quokkaO\||You won!kangarooO\|/|/ \You lost

Java Program ASAP   Please modify  Map<String, String> morseCodeMap = readMorseCodeTable("morse.txt"); in the program so it reads the two text files and passes the test cases. Down below is a working code. Also dont add any import libraries in the program just modify the rest of the code so it passes the test cases.    import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.util.HashMap;import java.util.Map;import java.util.Scanner;public class MorseCodeConverter {    public static void main(String[] args) {        Map<String, String> morseCodeMap = readMorseCodeTable("morse.txt");        Scanner scanner = new Scanner(System.in);        System.out.print("Please enter the file name or type QUIT to exit:\n");        do {            String fileName = scanner.nextLine().trim();            if (fileName.equalsIgnoreCase("QUIT")) {                break;            }            try {                String text =…
