Switch statements have a number of possible scenarios that can occur, based on the certain condition.

However, they only work with variables of type char, String, short, byte, and int.

Switch statement syntax:

switch(variable)

{

case 1: check variable;

Statements;

break;

case 2: check variable;

Statements;

break;

case 3: check variable;

Statements;

break;

default: statement;

}

Switch Statement Example:

char LetterGrade = ‘A’;

switch(LetterGrade)

{

case 'A' :

System.out.println("Awesome!");

break;

case 'B' :

System.out.println("Brilliant!");

break;

case 'C' :

System.out.println("Cool");

break;

case 'D' :

System.out.println("Definitely could improve");

break;

case 'F' :

System.out.println("Failed. Try Again.");

break;

default :

System.out.println("Not a valid grade");

}
