i wrote if (firstExample.equals(secondExample)) { //wrote the rest of the block right } What am i doing wrong here?

It says try again, but is my code correct?

Equality.java 
// I have imported a java.io.Console for you, it is named console. 
String firstExample = "hello";
String secondExample = "hello";
if (firstExample.equals(secondExample)) {
  console.printf("first is equal to second\n");
  System.exit(0);
}
String thirdExample = "HELLO";

Thank you that worked! But what i don't get is, in the tutorial it was instructed to place System.exit(0); afterwards. So i'm guess because it wasn't instructed to automatically exit the program that isn't needed then?

Mohammed Saeed Keep in mind that challenges are a little special. They have to be able to evaluate your code. My guess is here that if the system exits... well... they can't evaluate it anymore.

:information_source: It's a good idea (inside of challenges) to never do anything they don't explicitly ask for. Try not to implement variables they don't want etc. Even though the code may be fully functional outside the challenge, it can cause the challenge to fail.

I just did the challenge and passed the first task with this code:

// 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");

Yes, most of the time you just add specifically what you are told to. It usually gives you a hint whether it is the compiler throwing the error or the challenge just telling you that the code/answer received isn't what was expected.
