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

Hello, here I am again. The program is already working but I don't know how to align the output because it is so messed up. Hope you can help me again with this.

That clears it. I thought that the use of the indexOf("JAVA")!=-1 is to scan every 4- letter word from the start and when it does find the word "JAVA", there will be some values that is not equal to...

Its okay, I'm after the logic. I'll just ask my professor about it.

Can I ask some questions?
temp+=value; -> this is to store the value of the 4 strings to be formed right?

I don't get the -1...

I'm not familiar with Scanner but I think it is the same as BufferedReader?

@Norm
It is a statement.

Hmm, I'll try to fill it.

Enter a letter: J
Enter a letter: A
Enter a letter: C

First, I enter "J" followed by "A" which is to formed JAVA but I enter a "C" on...

@aussiemcgr
In our situation, it will only stop if the word JAVA is formed.

indexOf(String value) - I don't know this function yet because I think it is on more complex programming and I think...

Hello, I am new in this forum, hope you guys can help me with my problem.

Our professor gave us a take home quiz and I don't know what to do anymore after several attempts in doing the program. I...
