As a 20+ year C# developer that is looking at having to learn enough Java to code for one project, your videos are well done and helpful — even at 1.75 speed. Well done.
Thank you for the video, great work. Appreciate your work.
but where we can use that or when in what condition because i dont think so we will use it right ?
Very very useful video tq bro
Hello! Why you've n't take Arraylist class in this tutorial can u elaborate
I got here by using 2x speed, so does that make me 1/4th the way?
BRIEF HALFWAY POINT PARTY!….ok back to it
yay, I'm hafway through!
for those who are too, congrats! btw, we already completed 4 out of 6 hours of the course, even though we are halfway through the videos! hope that motivates you 🙂
Why can't we just sysout allGrades instead of going through the trouble of converting to an array? the output is the same
myArray = myArrayList.toArray(new Integer[myArrayList.size()]);
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 5
at java.util.Arrays$ArrayList.get(Arrays.java:3381)
at practise.main(practise.java:9)
this exception is raised in my program. typed it out exactly as you did
hey Caleb, I just put the following 2 lines and get the same result , what's the difference?? If there is a difference , can you tell me what is it???
Input Code :
List<Integer>allGrades= Arrays.asList(5,3,2,6,3);
System.out.println(allGrades);
Terminal :
[5, 3, 2, 6, 3]
Welcome to the halfway point.
Thanks for the free tutorials 🙂
Even when the video is 2 minutes you have to do the sponsor.
Next: *Sponsor taking longer than the concept being explained*. Would die of laughter.
Also as a side note: Your tutorials are amazing!
Halfway.
So what's the difference of using toArray() and your way?
If I learn all these 100 lessons, can I get a job in Java, or these are just basics?
That music at the end is so cringy lol but great content mah man
