count multiples of 6 between two numbers given by the user.
 
Hi all, Is my answer true .. and I want your opinion in my answer
• Write a program fragment to count multiples of 6 between two numbers given by the user.

:
  1. int X=30; 
  2. int Y = 60; 
  3. int count=0; 
  4. do { 
  5.         X++; 
  6.         if(X%6==0)  
  7.         { 
  8.                 count++; 
  9.         } 
  10. } while(X<Y); 
  11. System.out.println("Count of Multiplies=" + count );

Thank you..

I think you got it. Quick note though, the two number (X and Y) should be inputted by the user, not you, so you should probably ask for them.

Your logic is not quite correct. Try X=35, Y=35 or X=42, Y=48.

Hint: Use a while loop instead of a do/while loop. The latter should be avoided when possible. (There is another problem with your code, but I will let you figure out what it is.)

i pointed this out to him in his other post, as it was a very similar problem and he made the very same logically mistake as he has done here.

I have a tip; don't make it so obvious that you are doing homework problems. Goodness.

I agree with titaniumdecoy...don't use a do...while loop. Use a while loop (or I suppose a for loop would work in this case as well). Also, have X and Y be input. You could use a scanner or you could use a JOptionPane. Also, why do you increment X before you check to see if it's a multiple of six?
