The switch variable can be of

The correct answer is: C. both int as well as char type.

A switch statement is a control flow statement that allows you to execute a different block of code for each value of a variable. The switch variable can be of any integral type, including int, char, and short. It can also be of enum type.

Here is an example of a switch statement that uses an int variable:

``` int x = 5;

switch (x) { case 1: System.out.println("x is 1"); break; case 2: System.out.println("x is 2"); break; case 3: System.out.println("x is 3"); break; default: System.out.println("x is not 1, 2, or 3"); } ```

Here is an example of a switch statement that uses a char variable:

``` char c = 'a';

switch (c) { case 'a': System.out.println("c is 'a'"); break; case 'b': System.out.println("c is 'b'"); break; case 'c': System.out.println("c is 'c'"); break; default: System.out.println("c is not 'a', 'b', or 'c'"); } ```

Here is an example of a switch statement that uses an enum type:

``` enum Color { RED, GREEN, BLUE }

Color c = Color.RED;

switch (c) { case RED: System.out.println("c is RED"); break; case GREEN: System.out.println("c is GREEN"); break; case BLUE: System.out.println("c is BLUE"); break; default: System.out.println("c is not RED, GREEN, or BLUE"); } ```
