Hello. I am a new java programmer using Eclipse. I am following a tutorial off of lynda.com when I came across an error that I am not sure how to fix.

I am trying to create a simple calculator that receives two numeric values from the user and adds them together. My current code looks like this:
--------------------------------code---------------------------------------------------------------------
import java.io.*;

public class Calculator {

public static void main(String[] args) {
String s1 = getInput("Enter a numeric value: ");
String s2 = getInput("Enter a numeric value: ");

double d1 = Double.parseDouble(s1);
double d2 = Double.parseDouble(s2);
double d3 = d1 + d2;

System.out.println("The answer is " d3);

}

private static String getInput(String prompt) {
BufferedReader stdin = new BufferedReader(
new InputStreamReader(System.in));

System.out.print(prompt);
System.out.flush();

try {
return stdin.readLine();
} catch (Exception e) {
return "Error: " + e.getMessage();
}
}
}
--------------------------------------------code---------------------------------------------------------

I believe the problem has something to do with calling the "d3" variable that is adding the two numbers together. Let me know what you think and if you can help. Thanks!

Without telling us the actual error message, I can only point out that your call to System.out.println() is not valid syntax.

This is primarily a forum for people encountering issues specifically with Eclipse, not really one aimed at covering questions about the supported languages themselves. You'd find a more appropriate audience at http://www.javaranch.com/ and their "Beginning Java" forum at http://www.coderanch.com/forums/f-33/java (assuming Lynda has no such outlet of their own).
