Question

Describe the conditional statement in java that does not accept the Boolean datatype value in the conditional statement.

Answer 1

Switch is a conditional statement in Java that does not accept a boolean value in the conditional statement.

$\textsf{\Large Switch}$

   $\textsf{Syntax}$

       $\texttt{switch ( control variable ) \{}$

            $\texttt{case 1 :}$

                $\texttt{// statements}$

            $\texttt{case 2 :}$

                $\texttt{// statements}$

            $\texttt{case 3 :}$

                $\texttt{// statements}$

                 $\texttt{.}$

                 $\texttt{.}$

                 $\texttt{.}$

            $\texttt{case n :}$

                $\texttt{// statements}$

            $\texttt{de\hspace{-.5em} fault :}$

                $\texttt{// Last block}$

       $\texttt{\}}$

   $\textsf{Explaination}$

       A switch case statement is multiple branching statement where a

       particular statement is executed out of a number of options as per the

       user's choice.

       In this system, the control goes to a specific case and executes the

       statements for the given switch value.

       It also includes a 'default' case. The 'default' case is executed only when

       the switch value doesn't match any of the given cases.

   $\textsf{Terms related to Switch Case statements}$

       $\textsf{Switch Block}$

          A switch statement starts opening curly bracket '{' and ends with

          closing curly bracket '}' the cases which are enclosed within this

          which statement are known as the switch block.

       $\textsf{Break statement}$

          A break statement is used at the end of each case that is used as a

          case terminator.

          No statement is written after break in any specific case.

          This statement forces the control to exit from the switch block.

       $\textsf{Fall through}$

          If break statement is not used after case that control intersect the

          other case for execution this condition is known as fall through.

       $\textsf{De\hspace{-.3em} fault case}$

          This is a special case in switch case structure.

          It is executed when the value does not match with any of the case.
