How to compare a string's 1st character with a integer in java

Question

Example
String s="1234"
int i =1
I want to compare s[0] with i

Answer 1

boolean result = ( Integer.valueOf( s.charAt( 0 ) ) - '0' == i );

This assumes string <s> contains only digits.

As you know that String is a character of sequence and also String is a class which has method charAt(index) so you can get 1st character using charAt(0)

Since it will return character not integer so you need to get is as a integer using Integer.valueOf() method.

If you want to get 1st character using s[0] then you need to convert String in character array
