displays back to the user the decimal value and exits

program 1 description: 

Write a program takes in a binary value, protected by a try/catch block, from the console and displays back to the user the decimal value and exits. You can use Integer.parseInt(bin, 2). 
If input is not base 2, parseInt will throw an error, which the try block will catch and add display a meaningful message to user, then prompt for a binary number again.

Program 2 description:

Starting with the code hangeman.java and hangeman.txt which is located in the contents section, modify the code to read in the file hangeman.txt which will contain the words used for guessing. In addition improve the code to meet the courses rubric for full credit ( code comments ect ). The hangeman.txt should be in the root of the project, e.g. the parent of the src folder and you would open it with new File("./hangman.txt").

  • import java.util.Scanner;


    public class hangman {
      public static void main(String[] args) {
        String[] words = { "write", "program", "that", "receive", "positive" };
        char anotherGame;

        Scanner input = new Scanner(System.in);

        do {
          int index = (int) (Math.random() * words.length);

          String hiddenWord = words[index];
          StringBuilder guessedWord = new StringBuilder();

          for (int i = 0; i < hiddenWord.length(); i++)
            guessedWord.append('*');

          int numberOfCorrectLettersGuessed = 0, numberOfMisses = 0;

          while (numberOfCorrectLettersGuessed < hiddenWord.length()) {
            System.out.print("(Guess) Enter a letter in word " + guessedWord
                + " > ");
            String s = input.nextLine();
            char letter = s.charAt(0);

            if (guessedWord.indexOf(letter + "") >= 0) {
              System.out.println("\t" + letter + " is already in the word");
            } else if (hiddenWord.indexOf(letter) < 0) {
              System.out.println("\t" + letter + " is not in the word");
              numberOfMisses++;
            } else {
              int k = hiddenWord.indexOf(letter);
              while (k >= 0) {
                guessedWord.setCharAt(k, letter);
                numberOfCorrectLettersGuessed++;
                k = hiddenWord.indexOf(letter, k + 1);
              }
            }
          }

          System.out.println("The word is " + hiddenWord + ". You missed "
              + numberOfMisses + ((numberOfMisses <= 1) ? " time" : " times"));

          System.out.print("Do you want to guess for another word? Enter y or n> ");
          anotherGame = input.nextLine().charAt(0);
        } while (anotherGame == 'y');
      }
    }
