Why it is not working

It gives 25 errors but I dont understand why...

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");
}
if (noun.equalsIgnoreCase("hello") {
  console.printf("first and third are the same ignoring case");
}
    }

Barisan,

You do have undefined/undeclared variable in your code "noun" I think you meant "firstExample" or "thirdExample" instead. Try it and it will work:

(((String firstExample = "hello"; String secondExample = "hello"; String thirdExample = "HELLO";

if ( firstExample == secondExample ) { console.printf("first is equal to second"); } if (thirdExample.equalsIgnoreCase("hello")) { console.printf("first and third are the same ignoring case"); } )))
