Answer 2

Use
int n= Integer.parseInt(in.nextLine());

instead of
int n=in.nextInt();

Answer 3

If your input is like this it works.
Input:
2 Name1
Name2
Ouput:
N
It's because your a still on the first line after nextInt and nextLine finds a Space as first char.

Answer 4

That's because a String itself can throw this exception.
It's not the array who is throwing it.
And your first string at Index 0 is empty.

Answer 5

Exception in thread "main" java.lang.StringIndexOutOfBoundsException:

index out of range: 0 at java.base/

java.lang.StringLatin1.charAt(StringLatin1.java:48) at java.base/java.lang.String.charAt(String.java:711) at Program.main(Program.java:18)

I think the main problem is in line 18
Char ch=a[i].charAt(0);
It is saying the index of the string is not 0 or the compiler can't find any character in that position. But as a learner, I know every string starts with a position 0, but why this error is coming everytime I don't know.
