Don't know what's wrong...

I'm not having any bugs in the Preview, but still unable to go to the next quiz.

Equality.java 
// 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");
System.exit(0);
}

In general you will not want to (or need to) use System.exit(0) unless the instructions explicitly state that you should exit out of the system immediately.

Thank you very much for the advice! I now understand that not all the time we need to use the System.exit(0) code.

Remove the 'System.exit(0);' and you'll be good.

Thank you. But the lecture video said we had to have the "System.exit(0);" line when using an "if" statement. How do we tell when to use and when not to use?
