How do I use "if" statement to compare two stings to see if they are equal.

I am trying to do the challenge for Equality java but when I try to compare the two strings the way I was shown how to in the video it comes out wrong. I am not sure where my error is. I looked up on google how to but could not find what I was looking for.

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

Hey Jonathan,

additionally to Jacobs advice I see a dot here

console.printf("First is equal to second".);

change it to 

console.printf("First is equal to second");

and a typo in your secondExample variable:

if (firstExample.equals (secondExemple)){

change it to:

if (firstExample.equals (secondExample)){

So your code should look like this :

// 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");
}
String thirdExample = "HELLO";

Keep on coding bro ....

Hi! It looks like you accidentally put a semicolon on the fourth line (at the end of the first line of the if-statement). Try changing this "if (firstExample.equals (secondExemple));{" to this: "if (firstExample.equals (secondExemple)) {", and see if it helps!
