Answer 1

original code:

int question,
String answer;

Corrected code:

int question, answer;

question = input.nextInt ();

 if (question == 3*6*4)  { ... }

Updated code below:

  import java.util.Scanner;
  class Main
  {
    public static void main (String[]args)
    {
      System.out.println
      ("How much dirt is there in a hole 3 ft deep, 6 ft long and 4 ft wide? ");
      Scanner input = new Scanner (System.in);
      String ans;
        ans = "None";
      do
        {
          int question, answer;
            question = input.nextInt ();
          if (question == 3*6*4)
            {
              System.out.println ("Correct! or else it wouldn't be hole.");
              break;
            }
          else
            {
              System.out.println ("Wrong, try again.");
            }
        }
      while (ans.equals ("None"));
    } 
    
  }

I still get an error code when entering the correct answer.

Below is a sample run ,where I enter integers only.

How much dirt is there in a hole 3 ft deep, 6 ft long and 4 ft wide?                                                            
5                                                                                                                               
Wrong, try again.                                                                                                               
72                                                                                                                              
Correct! or else it wouldn't be hole.                                                                                           
                                                                                                                                
                                                                                                                                
...Program finished with exit code 0                                                                                            
Press ENTER to exit console.

If normal ints are given ithe input the prog works fine ,for string the code throws exceptions.Using try-catch blocks should take care of that.

But I am not sure if the above working is what u expected.
Perhaps share a few sample cases with  input & the expected output.
