Suppose s is a string with the value "java". What will be assigned to x if you execute the following code?

char x = s.charAt(4);

a. 'a'
b. 'v'
c. Nothing will be assigned to x, because the execution causes the runtime error StringIndexOutofBoundsException.

c The string index starts from 0 and the last index is s.length() - 1 . s.charAt(4) is out of bounds.
