Thanks! I'll give it a go later, I need to get some rest first, busy day for me.

Do I have to change the entire program or I just add something to it with regards to newbie's post?

Got It!


OUTPUT:


Can you help me with the whitespace so that I can enter "20+5" instead of "20 + 5".

I'm sorry but I don't really know how to use Scanner. I've tried some but I ended up the same with using BufferedReader.

@Sean4u
Yes! that's what I'm saying. Can you help me with the java.lang.Scanner because we are not using it in our class.

Let me put it this way. Let say I want to ADD 3 and 5. So the computer will ask me to enter/input my equation which is "3+5". Then, the computer will display the sum which is 8.

INPUT: 3+5
SUM: 8...

"3+5" there was supposed to be an input but they are equivalent to 3 variables which is (num1, operation, num3)

OUTPUT
Enter Operation: +
Enter Number 1: 3
Enter Number 2: 5

* end of program *
But our professor wants us to have an output like this,

OUTPUT
Input: 3+5
