Practice as switch statement. We want to code a calculator.

Design and code a Java program that accepts an expression from the user in the form var$1$ op Var$2$ where var $1$ and var $2$ are double values and op an operation $,$ or $**)$ eg$.3\mathrm{.}4**2\mathrm{.}3$

Your program reads a double followed by a character then another double.

shitch on the character, in case it's a $+$ then perform the addition and display the result

in case it's $-$ do the subtraction, in case it's $**$ do the multiplication and in case it's $/$ do the division. $*1$
