I get the prompts for entering in a name, an adjective, etc. However, when the prompting for words is finished, I get this output in the console below.
at java.util.Formatter$FormatSpecifier.<init>(Formatter.java:2720)
at java.util.Formatter.parse(Formatter.java:2560)
at java.util.Formatter.format(Formatter.java:2501)
at java.util.Formatter.format(Formatter.java:2455)
at java.io.Console.format(Console.java:170)
at java.io.Console.printf(Console.java:209)
at TreeStory.main(TreeStory.java:21)
Can anyone please point out problems with my code? Thanks in advance!
import java.io.Console;
public class TreeStory {
public static void main(String[] args) {
Console console = System.console();
/* Some terms:
noun - Person, place or thing
verb - An action
adjective - A description used to modify or describe a noun
Enter your amazing code here!
*/
// __Name__ is a __adjective__ __noun__. They are always __adverb__ __verb__.//
String name = console.readLine("Enter a name: ");
String adjective = console.readLine("Enter an adjective: ");
String noun = console.readLine("Enter a noun: ");
String adverb = console.readLine("Enter an adverb: ");
String verb = console.readLine("Enter a verb ending with -ing: ");
console.printf("Your Treestory:\n--------------\n");
console.printf("% is a %s %s. ", name, adjective, noun);
console.printf("They are always %s %s. \n", adverb, verb);
}
}

Jeremy Hill
29,567 PointsThat would print the title- "Your Treestory" with a dashed line underneath it. It sounds like there will be more information to follow.
It looks like it is set up as a title.

29,567 PointsAfter looking at the code above it will print these two lines underneath what you are asking about:
console.printf("%s is a %s %s. ", name, adjective, noun);
console.printf("They are always %s %s. \n", adverb, verb);

29,567 PointsIf you are wanting to understand how it is written:
The "%s" is a place holder for a variable after the comma that follows the ending quotes. The "\n" is a new line character; any time that you see that in code that means that whatever follows that will be on the next line in the output.
The variables at the ends of the lines of code that I mentioned are created earlier in the code; something is eventually put into the variable and then it is being inserted into their printf output.
The programmer can make any kind of variable they want as long as they follow the syntax rules. They can make a variable equal to some calculation or make it equal to user input and then later print it out as part of the program.
I hope this makes sense to you. Let me know if you are still struggling with the concepts here.
