Declaration and Access Control What will be the output for the below code?static public class Test{ public static void main(String[] args){ char c = 'a'; switch(c){ case 65 : System.out.println("one");break; case 'a': System.out.println("two");break; case 3 : System.out.println("three"); } }} two Compile error - char can't be permitted in switch statement. None of these Compile error - Illegal modifier for the class Test; only public, abstract & final are permitted. one two Compile error - char can't be permitted in switch statement.
