Answer 4

I want a user to enter two numbers then again to enter an operator (+ ,- , *, / ) such as
Enter two numbers: 12 15
Enter an operator : +
12 + 15 = 27
Qn: I used nextInt() to scan 12 and 15
what do I use to scan the + sign!?

Answer 5

We can use next() from Scanner class. It is basically used to accept single line strings but it can also be used to accept single characters.

Maybe there is a method in BufferedReader class, I'm not aware of it though as I don't use it much.

Answer 6

Also we can always use switch. List all the operators in the cases and match them and perform the required operation.
