error message

I am running this code:

String answerToLife = "42"; String parseInt; answerToLife = console.readLine ("42"); int age = Integer.parseInt(answerToLife);

and keep getting an error message on the "c" in console on the third line.

ParsingInts.java 
String answerToLife = "42";
String parseInt;
answerToLife = console.readLine ("42");
int age = Integer.parseInt(answerToLife);

Hello there!

One issue you may be having is the space between readLine and the information you're passing to it ("42").

I removed the space but keep getting the same error message.

Hey, Not too sure if it will fix your issue, but you might have to rename your variable name on line # 2 to something else other than "parseInt".

Hello, I have taken the advice given and reqritten the code but keep getting this error:

JavaTester.java:43: error: cannot find symbol answerToLife = console.readLine("42"); ^ symbol: variable console location: class JavaTester 1 error

I removed the last line of the code shown above, taken away the space after readLine, and removed the String parseInt line as well, but keep getting this same message.

Thanks a lot.

This is how I edited your code so it works:

import java.io.Console;

public class ParsingInts {

 public static void main(String[] args) {
Console console = System.console();
String answerToLife = "42";
String parseInt;
answerToLife = console.readLine("42");}}

As you see, you have to define what "console" means. ( line 6 )
