Doubt in the video

[kalindiyadav5 (Kalindi .)]

In this video how mam uses the display function when it is not present?
The function is made but there is nothing inside the function.
When I put the exact function the answer comes!

Hey @kalindiyadav5
display function inside the Arrayops class

[kalindiyadav5 (Kalindi .)]

public static void display(int[] arr) {
for (int i = 0; i < arr.length; i++) {
System.out.println(arr[i]);
}

This should be there ? for the function to work

[Monu-Singh-480654572341490 (Monu Kumar)]

@kalindiyadav5 Yes
exactly

display fun code is available .
It’s just hidden
These are available inside the display fun
for (int i = 0; i < arr.length; i++) {
System.out.println(arr[i]);
