Everything seems right. Even went to questions to check and it looks right. But still get "bummer"!

// I have imported a java.io.Console for you, it is named console.

String firstExample = "hello"; if (firstExample.equals(secondExample)) { console.printf("first is equal to second"); } String secondExample = "hello"; String thirdExample = "HELLO";

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

Hi Bobby,

All languages including Java; read from top-to-bottom, what this means is if a variable doesn't exist in the compilers memory yet, it won't know anything about it, therefore an error will be thrown. This is the case with the code above as you've declared your IF statement before secondExample instead of after it which results in the below error.

JavaTester.java:106: error: cannot find symbol
if (firstExample.equals(secondExample)) {
                        ^
  symbol:   variable secondExample
  location: class JavaTester
1 error

To resolve this, you simply need to move the IF statement further down to where secondExample has been declared and parsed by the compiler.

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

if (firstExample.equals(secondExample)) {
  console.printf("first is equal to second");
}

Happy coding!

Hey, Chris! Thanks very much. That worked perfectly. I can't believe (nor do I want to say!! ;-) ) how long I struggled with this one!!! Thank you, Bobby
