Java Java Basics Perfecting the Prototype String Equality

equalsIgnoreCase not working!

I cannot for the life of me find out where the fault is. It keeps telling me to make sure I am using the equalsIgnoreCase and the console.printf

All help appreciated - thanks in advance!

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

Hi Olexa,

Your code is pretty much correct, expect you have a space between the method name and the parenthesis for both methods. This is what is causing your error. Just remove the spaces and the rest looks good.

Nice work! :) :dizzy:

Hi Jason

Still doesn't seem to be working. I also updated my code to remove == and use .equals to see if that helped (it didn't).

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

It looks like you changed the code that was for the first Task? That code need to be left untouched. The first challenge is looking for a comparison of the first and second example with the string being printed: "first is equal to second". This will be the first if statement.

The second task looks for the first and third ignoring case... this will be the second if statement and prints out "first and third are the same ignoring case". The first if statement should not be touched or changed for this task, but rather the second one just added under the first.

Also, watch your capitalization for the strings. The instructions have all the strings lower case, but you have some capital letters. Challenges are very specific and instructions need to be followed exactly.

You have all the syntax correct :thumbsup:, you just need to change the above to match what the instructions are asking for.

:)

Thanks. I ended up just resetting it and this time it worked. Not exactly sure where I went wrong and can't go back to compare - but it worked! Onward and upwards - thanks Jason!
