Is it possible to start off by writing the code instead of pre-writing the code? This will help students understand the process/steps more.

I understand most of the coding your using, but I can't see which part of your code tally's the number of times the same total is received by throwing two dice.

I guess I just have one question about the rolldice example.

Why are you adding one plus the random number (up to 6)? that would mean you could get 7 as a roll? or are you already compensating for the 0 roll by adding 1 to the random number (up to but not including 6)?

hello, in the rolldice example .
total[index]=0;
that mean all the index value or the elements are 0?
or the array start from index 0.

  • An Array is a Java variable object that can hold multiple values
  • An Array is similar to a table or grid of data
  • Values stored in Arrays are called “elements”
  • All elements are indexed with a numbering systems that starts with zero
  • Arrays can be one-dimensional lists, or two-dimensional grids of data
