Answer 1

@Meharban
:D Sorry, seriously... missing "" at string init.

Answer 2

@Meharban
"Meharban Singh"

Answer 3

String name='Meharban Singh";
name.substring(4,6);
This would return "rb"
Hence 4,6 means start from index 4 and end when (6-4=2) characters are selected (space is also a character)
Substring is sub-string(subset) of a particular string.
In your.case, you are selecting substring from the first letter until i characters are selected.

NOTE :- In java index starts from 0.
