Java switch

3. Conditional Statement switch

• To choose one option from more options then we should go for this switch statement.
• To choose one option from more options we can go for if_else_if statement but using switch is the best solution.

syntax

switch(variable)

{

       case value 1: statement1;

                          break;

       case value2:  statement2;

                          break;

       default: default statement;
