Need help with an arrays program

Question

this is the task
1.instantiate an array to hold integer test scores
2.determine and print out the total number of scores
3.determine whether there are any perfect scores (100) and if so print student numbers (who received these scores)
4.print out only the scores that are greater or equal to 80
5.calculate the percentage of students that got scores of 80 or above (and print out)
6.calculate the average of all scores (and print out)
heres the code that i came up with
int [] scores = {79, 87, 94, 82, 67, 100, 98, 87, 81, 74, 91, 59, 97, 62, 78, 66, 83, 75, 88, 94, 63, 44, 100, 69, 87, 99, 76, 72};
int total=scores.length;
System.out.println("The total number of scores is: "+total);
for (int i=0;i<=scores.length;i++)
System.out.println(scores);
step 2 is as far as i got
i got stuck at step 3, i cant figure out how to do that
reply plz, ty

Answer 1

3.determine whether there are any perfect scores (100) and if so print student numbers (who received these scores)This question strongly suggests that the data contains information about students associated with each of the test scores. As you have illustrated it, part 3 is simply not doable. There must be more to the assignment than you have said.
Do one thing at a time and make sure your code compiles and runs as you expect before moving on. The code you have posted looks OK for the first couple of steps, but its it's impossible to say unless you post something that's runnable.
(A small thing - but very much appreciated - can you please post code using the "code" tags? Put {code} at the start of your code and again at the end. That way the code will be nicely formatted by the forum's astounding software.)
