how is this wrong????????????????????????????????????????????

I think I'm doing everything correctly here. I did it the same way in the TreeStory exercise and it worked just fine. Is there a bug here?

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

All right Paul,

There is a couple things with your code.

  1. There should be 2 of if statements the first seeing if the firstexample = the secondexample and the second if seeing if the firstexample = the thirdexample

  2. Instead of "HELLO" it should be thirdexample

All in all the code should look like this

// 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(firstExample.equalsIgnoreCase(thirdExample)){
console.printf("first and third are the same ignoring case");
}

If this helps, please make this the best answer.

Thank you! Sorry about the obnoxious punctuation earlier. I was quite frustrated.
