Flow Control - Programming

Q1:

switch(x) 
{ 
    default:  
        System.out.println('Hello'); 
}
Which two are acceptable types for x?
  1. byte
  2. long
  3. char
  4. float
  5. Short
  6. Long

A 1 and 3

B 2 and 4

C 3 and 5

D 4 and 6

ANS:A - 1 and 3

Switch statements are based on integer expressions and since both bytes and chars can implicitly be widened to an integer, these can also be used. Also shorts can be used. Short and Long are wrapper classes and reference types can not be used as variables.
