Define a string variable named first Name that stores your name?

So, building ontop of the first line of code that we added, for Part 2 of the coding challenge we would add:

String firstName = "Darrell";
console.printf("Darrell can code in Java!");

Now part 3 of the challenge is where we make use of our variable. We can replace the actual word "Darrell" in our printf with a %s, which is a placeholder for our variable. This looks like the following:

String firstName = "Darrell";
console.printf("%s can code in Java!", firstName);

When the above code runs, it will replace the "%s" inside of the string with our firstName variable.

Hope this helps, I know it can be confusing at first but keep at it :)

Hi, Thank You for trying too help me. I input that second code and it gave me a error.

Which part of the coding challenge are you on?

For part 1 I tested entering only the following and nothing else and it passed for me

String firstName = "Me";

For the second and third part we will add the printf statements

Hello again! The "%s"=String Placeholder (s= String). It is basically telling the compiler to expect a variable of type String. If the variable was an integer type we would use %d to represent it instead.

Your code below is close:

console.printf("%s Darrell can code in Java!"); 

However we must also specify which String variable the %s is going to be replaced with. You can add this parameter as such:

console.printf("%s can code in Java!", firstName); 

We can also remove your name, because that is stored in the firstName variable.

Awesome :) I am glad that I could help! And if you have any other questions I would be more than happy to help

Hello again, in order to ensure that both conditions are true we use a logical AND which is "&&" such as

boolean shouldContinue = isRefreshed && isReadyToGetStarted;

Could you please post the link to the video/challenge that this is for so that I can better help

The above question involving && is from the java objects course. This above link is to the java basics course. I am not sure which you are working on, but for the Java Objects question involving

boolean shouldContinue = isRefreshed && isReadyToGetStarted;

Since this is for a quiz, they would only want you to enter the && into the input box:

&&

so the above would be the answer

Haha yes I understand the slacking definitely, I need to study more. So for the challenge it is broken down into 3 parts. They have setup everything else so going through the challenge part by part.

For part 1 it says: "Define a string variable named firstName that stores your name. Set the value to your name. "

To do so, in the challenge window we would type:

String firstName = "Darrell";

We have now stored the value "Darrell" in the first firstName variable. Everytime we call firstName, it will have Darrell

For part 2 it says: all the printf method on the console object and make it write out "<YOUR NAME> can code in Java!"

To do this, we want to add the following code under what we just created. (on line 3 if "String firstName = "Darrel" is on line 2)

console.printf("Darrell can code in Java!");

Now part 3 says: Now replace <YOUR NAME> in the console.printf expression with the firstName variable using the string formatter.

To do this, we want to Modify (or REPLACE) the statement we entered in part 2 like such:

console.printf("%s can code in Java!", firstName);

the "%s" is representing a string variable, which is specified as "firstName".

Hope you pass now!

The reason we do not have public static main in here is specifically because of the treehouse challenge coding area. Treehouse has programmed it in a way that that stuff(public static main etc) is taken care of , so they don't require that you enter it.

The public static main method is part of what we call the "boiler plate". If you were making the file on your computer or using the workspaces at treehouse and compiling it (NOT in the code challenge), you would include:

public class Filename {
     public static void main(String[] args) {
     //Code goes here
    }
}

and you would have the file Filename.java.

There are videos that will explain what the public static void main method is and what it does etc. So don't worry about any of that right now!
