12 12 Two-Dimensional Arrays n In Java, 2D array implemented internally as array of arrays n but externally syntax of 2D array may seem easier to use n Typical control structure for computing with 2D array is nested loop n loop within another loop n Let's write program to n load array with values shown n print contents of array 01230123 0 1 2 0 0 0 0 1 2 0 2 4 0 3 6 rows columns

20 20 Example: Per-Student Averages n 2D array n each row is student in course n values in each row represent student's quiz scores in course n Print average quiz score for each student n for each row of scores n add up scores n divide by number of quizzes in a row n approach: nested loop 0123401234 95 82 13 96 51 68 63 57 73 71 84 78 50 50 99 70 32 12 scores 0 1 2 3 average of row 0 is 71.5 average of row 1 is 59.75 average of row 2 is 76.5 average of row 3 is 50.0 average of row 4 is 53.25

24 24 Sorting n Computers are essential for keeping track and finding large quantities of data n Finding data when necessary is much easier when data is sorted in some way n computer people think a lot about how to sort things: n finding medical records n banking information n income tax returns n driver's license information... n even names in a phone book... n all depend on the information being sorted
