Code Challenge: Blog Reader Project Overview Question 4

Hey there stuck for question 4 of the Blog Reader App

Question:

Finally, write the 'message' variable to the log using the Log.d() method. For the first parameter of Log.d() (the tag), use “CodeChallenge”, and use the 'message' variable as the second parameter.

My Answer:

String title1 = "Android is awesome";
String title2 = "Mike is cool";
String title3 = "Treehouse loves me";

String[] titles ={ title1, title2, title3};

String message = title2;
Log.d(“CodeChallenge”,"message");

Please help ?

First, we should take care of another problem. Your code should not have passed question number 3.

You entered:

String message = title2;

but the question asked "Now add a new String variable named 'message' and set it equal to the second element in the array." The answer Ben Jakuben is definitely looking for is:

String message = titles[1];

Now onto question 4:

You tried to enter the variable with quotations around it. Java would take this literally and your Log message would have just read "message". This defeats the purpose of trying to use a variable.

Here is the correct answer:

String title1 = "Android is awesome";
String title2 = "Mike is cool";
String title3 = "Treehouse loves me";
String[] titles = {title1, title2, title3};
String message = titles[1];
Log.d("CodeChallenge", message)

Keep coding!

Hey Adnan,

In the Log.d() function, the second parameter should be the message variable, but in the code in your post, you have it passed in as a String.

The answer by the mod forgot the ";" which means the complete answer is 

String title1 = "Android is awesome";
String title2 = "Mike is cool";
String title3 = "Treehouse loves me";
String[] titles = {title1, title2, title3};
String message = titles[1];
Log.d("CodeChallenge", message);
