    int firstnumber, secondnumber, thirdnumber, answer;
    firstnumber = 100;

    System.out.print("Total is " + answer);
    you can see above that there is no In and Run was successfull
    It isnt IN as you believe, but LN, short for line (see: println).
    The difference is that println ends the string with a new line character, whereas print does not.

    For your second issue, you never defined "user_input" anywhere. Before you use it, you need to say Scanner user_input = new Scanner(System.in);

    Working the problem right here in the forum is fine. That's what it's for.

    Read the Announcement topic at the top of the sub-forum to learn how to post code in code or format tags. Post the code causing the error and the EXACT error message/stack trace, copied and pasted from just as it appears in your terminal. Telling us "there is error" is not helpful, at least not as helpful as you could be.

    ok thanks

    --- Update ---

    for the scanner i have that in place immediately after
    public class void main(string[] args) {

    still have error (something like a small bulb and a red dot on that line

    then on the import java.util.Scanner; (line i have something like a red caution mark there)


    do i need to delete the comments?

    thanks

    import java.util.Scanner; needs to be above public class JavaApplication5 and under package javaapplication5;.
