Hi Solomon,
Don't worry, this can happen to all of us.
It looks like you're creating a String variable from console.printf, which you can't do. You may be getting a incompatible types error similar to this.

error: incompatible types: void cannot be converted to String

Be sure to follow the instructions carefully, you won't be creating a variable for the last two tasks. It wants you to print the values of the variables you created. For this challenge, console.printf requires a few things which are noted in the videos preceding it, please re-watch them to get a more in-depth explanation. [1] It starts around the 3 minute mark.
You can print a string to the console like so
Java
console.printf("Hello there");

Or you can print strings and variables
``` Java
// %s is for String
// %d is for digit
String myName = "Tristan";
console.printf("Hi my name is %s.",myName);
```
Here's a doc that shows more info on the types [2]
You'll place the %s or %d where you want the value of the variable to show when it's printed.
My example above will look like this
terminal
Hi my name is Tristan.

If I put the %s at the beginning, it may not make sense, but it will work.
Java
String myName = "Tristan";
console.printf("%s Hi my name is.",myName);

The output would be
terminal
Tristan Hi my name is.

I hope that helps. If you come across issues like this, the solution is usually in the videos. When I took this track I re-watched them several times, it helped a ton.
