Hi Jay,

You should compare for equality of a string using the .equals() method. For other datatypes you can compare with a double-equals, ==, but not for Strings. Use dot notation on the first string variable and pass in the second string variable as the parameter to the .equals() method, i.e. put the second variable name inside the parentheses.

You also need to close your curly braces after the semi-colon.

Try something like:

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

I hope that helps,

Steve.
