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”);
}
