Answer 1

Look, boolean datatype can take the values true or false... U initialized the boolean variable, "isVowel" with false... It means isVowel=0 initially... When it entered to switch... If any of the case becomes true it is assigned with true ie., 1.... Hope you got the point... 👍

Answer 2

Yeah!! Surely,
The java.util.Scanner.next() method finds and returns the next complete token from this scanner. A complete token is preceded and followed by input that matches the delimiter pattern. This method may block while waiting for input to scan, even if a previous invocation of hasNext() returned true.
It takes a single character which is at 0th index..ie.,charAt(0)
