Why do we need the for each loop? You can just reverse-sort and sysout allGrades and it would be the same?

[manojbanik]

you don't need the for loop to print the sorted arraylist

[darkfire_]

for some reason Collections.sort(allGrades); is not working i imported using import java.util.ArrayList;, but it doesnt work


i also have these in the program:

import java.util.Scanner;
import java.util.Arrays;
import java.util.LinkedList;
import java.util.List;
