Hi im new in Java. i have this case study and i don't know how im gonna do it.
my professor wants me to create a menu or message box that has 3 options
[ 1 ] Addition
[ 2 ] Subtraction
[ 3 ] Exit
*________ this signifies a input box
if i will choose option [ 1 ] there should be another message box that will appear. inside this message box is an input box that lets u input two numbers and it will perform addition.
same as subtraction. and etc.
