- * Syntax of switch statement is
- *
- * switch(expression){
- *
- * case value1:
- * //statements
- * break;
- *
- * case value2:
- * //statements
- * break;
- *
- * ....
- *
- * default:
- * //statements
- * break;
- *
- * }
- *
- * here, expression must be of type int, short, byte or char.
- * values should be constants literal values and can not be
- * duplicated.
- *
- * Flow of switch statement is as below.
- * Expression value is compared with each case value. If it
- * matches, statements following case would be executed.
- * break statement is used to terminate the execution of
- * statements.
- *
- * If none of the case matches, statements following default
- * would be executed.
- *
- * If break statement is not used within case, all cases following
- * matching cases would be executed.
