Common Manipulations of a 2D Array

• This applet illustrates several common manipulations of 2D arrays:
  • minimum
  • maximum
  • average
  • printing the array as a table
• The method of visiting each element can be essentially the same.
• How would you modify these loops to handle the case where each row does not have the same number of columns?
• Why might you not always use this more general method?
