[dokunbam]

Am a beginner and am learning on my own
i started two days ago and am getting on fine

but i have a problem now, some should pls help out


i started with JAVA somedays ago and i think am getting well on it
But the problem i have now is that some of the code written on the material are somehow different wen i work on java IDE

package javaapplication2;

public class main {

public static void main(String[] args) {


int firstnumber, secondnumber, thirdnumber, answer;
firstnumber = 100;
secondnumber = 75;
thirdnumber = 25;

answer = (firstnumber * secondnumber) / thirdnumber;

System.out.print("Total is " + answer);

you can see above that there is no In and Run was successfull

But the material says printIn. y is that so cos its confusing
----------------------------------------------------------------------------------------------------


another one now is

package javaapplication5;

public class JavaApplication5 {


import java.util.Scanner;

public static void main(String[] args) {



String firstname;
System.out.print("Enter Your First Name Here"wink;
firstname = user_input.next();

String secondname;
System.out.print("Enter Your Family Name Here"wink;
secondname = user_input.next();

String fullname;
fullname = (firstname + " " + secondname);

System.out.print("You are" + fullname);

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;.
