proving a statement is equal to another with a boolean

I don't know what is wrong with my code. It says that I have a compiler error and I don't remember what to do.

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 = secondExample) {
  console.printf("first is equal to second");
}

When you have just a single '=' it tries to set one thing equal to another; when checking for equality you need to use either double equals '==' or .equals(). In this case you should be using the .equals() method: 

 if(firstExample.equals(secondExample){
// do something
}

Nice job Jeremy! Missing a trailing parenthesis there at the end...to close the one you opened with the if statement.
