pulling a character index from a string code example

Example 1: get certain character from string java

String words = "Hi There"; //creating a string var named 'words'
char index = words.charAt(0); /* setting a variable 'index' to letter
'0' of variable 'words'. In this case, index = 'H'.*/
System.out.println(index); //print var 'index' which will print "H"

Example 2: certain position in string

String anotherPalindrome = "Niagara. O roar again!"; 
char aChar = anotherPalindrome.charAt(9);
