error: Are you sure you used the `equals` method of `firstExample` and then called `console.printf`?

it looks like I have my code all right but it saying: Are you sure you used the equals method of firstExample and then called console.printf?

Equality.java 
// I have imported a java.io.Console for you, it is named console. 
String firstExample = "hello";
if(firstExample.equals("secondExample")) {
  console.printf("first is equal to second");
}
String secondExample = "hello";
String thirdExample = "HELLO";

secondExample shouldn't be in quotes and the if statement should be at the very bottom:

// I have imported a java.io.Console for you, it is named console. 
String firstExample = "hello";
String secondExample = "hello";
String thirdExample = "HELLO";
if(firstExample.equals(secondExample)) {
  console.printf("first is equal to second");
}

I've just looked through your comment and I am wondering why the secondExample is not in quotes, because the video shows ("dork") in quotes, hence why i did the same. Please explain if you know why. It will be helpful!

Because you don't want to compare the name of the variables. You want to compare the strings that the variables are holding, and to get to those strings you need to use the variable names without quotes.
