Answer 1

Are you trying to concatenate the arrays or the strings?

Answer 3

Thanks alot🔥

Answer 4

Well you have several problems with your code.
1. There isn't a concat method for Array or Arrays.
2. You didn't import Array or Arrays etc
3. You have syntax errors trying to use [] square brackets for your arrays or for the the method call (not sure which you intended due to placement). Parentheses are used with method calls. So if there were a concat method for the Array class then it would look more like;
Array.concat() // doesn't exist
Then arrays are made using curly braces {} like;
{1,2,3,4,5}

Answer 5

Can you please modify and send me the code

Answer 6

Javascript is not the same as Java.

Answer 7

You are using Array declaration and concatenate methods of js in Java.
That works in js . But not in Java.

Answer 8

Well, I'm not learning but I'm always in a class where java is being taught. The .concat() method you used only works in Javascript but not Java as both are not related in anyway.

Answer 9

Array
