Courses Plus Student 353 PointsWhich is the difference between this codes?
This is the teacher's code:
import java.io.Console;
public class TreeStory {
public static void main(String[] args) {
//Variables and constants
Console console = System.console();
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: ");
//Actions
console.printf("Your TreeStory:\n-----------------\n");
console.printf("%s is a %s %s. ", name, adjective, noun);
console.printf("They are always %s %s.\n", adverb, verb);
}
}
And this is my code:
import java.io.Console;
public class TreeStory {
public static void main(String[] args) {
//Variables and constants
Console console = System.console();
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: ");
//Actions
console.printf("Your TreeStory:\n-----------------\n");
console.printf(name + " is a " + adjective + " " + noun + "\n");
console.printf("They are always " + adverb + " " + verb + " " + "\n");
}
}
Well, I mean, in the end, my code has some disadvantage or something? Because in the "Challenge task" does not accept my code :(

10,424 PointsThe "difference" between the two snippets would be that the teacher's code correctly uses string formatting, and your code uses string concatenation. String formatting is much easier to localize than concatenation.
