I think you need to change the batteries in your smoke detector.

[ferdinandtugano]

Viewer suggestion: play it 1.5x speed. Thank me later.. nice tut btw.

[josephkreifelsii]

Nower days, you don't need to repeat <Integer>, java will use what you started with. SO you can do it this

ArrayList<Integer> myNums = new ArrayList<>();

I spent 30 minutes trying to figure out which of my smoke alarms needed new batteries...

[thereareclouds]

I agree with most of what's been said before me in this comment section. This video was great. Easy to follow.

U may choose not to  create any initial size of the array list

4:09 Lol he typed a heart out of nowhere

[mquanit]

"trimtosize()" is just useless its automatically trimmed by interpreter....

[who]

I kept getting an error (apparently benign) whenever I compiled. Code was originally:
ArrayList<String> people = new ArrayList();

Noticed that you added <Int> after the new ArrayList so did this with mine and no more annoying error !

Thanks!

make a video on multidimensional arraylist and how to insert and search in it

[TheWolfPackFam]

[innigaadu]

Where can I get good practice exercises to learn Java Topic wise & solutions ?

[adambaseball]

Time to post a video on how to replace a smoke detector battery!

[shakjosh]

nice Work
Please Upload J2EE, Struts, Hibernate, Spring Videos

[JasonErdmann]

every time you cut and paste a variable it takes you longer than it would have taken to just type it out, just type short things

[SmartProgramming]

nice work sir, good explanation, keep it up 👍👍

[TheBoredTraveler]

package lesson1;

import java.util.ArrayList;

public class myClass {


public static void main(String[] args) {

ArrayList<Integer> myList = new ArrayList<Integer>(5);
myList.add(5);
myList.add(20);
myList.add(45);
myList.add(10);

for (Integer x : myList)

System.out.println(x);

}
}

can we have a moment of silence for the smoke detector in the background?

[johnszarowski]

This is probably a helpful video. I'm not sure though, because I'm too busy wondering if anyone changed the batteries in the smoke alarms since this video was posted 8 years ago.

[noudie]

Thank you so much. very helpful ...I just have one question can I leave the initial size empty ?
