Challenge Task 1 of 2 The method getTitleFromObject will be called and passed a String and/or a com.example.BlogPost. For this first task, return the object obj type casted as a String if it is in fact a String.
I've included BlogPost.java for your reference only.
import com.example.BlogPost;
public class TypeCastChecker {
public static boolean HINT_1_ENABLED = false;
public static boolean HINT_2_ENABLED = false;
public static String getTitleFromObject(Object obj) {
String result = "";
BlogPost nowa;
if (obj instanceof String) {
result = (String) obj;
} else if (obj instanceof BlogPost) {
nowa = (BlogPost) obj;
result = nowa.getTitle();
}
return result;
}
}
import com.example.BlogPost;
public class TypeCastChecker {
/***************
I have provided 2 hints for this challenge.
Change `false` to `true` in one line below, then click the "Check work" button to see the hint.
NOTE: You must set all the hints to false to complete the exercise.
****************/
public static boolean HINT_1_ENABLED = false;
public static boolean HINT_2_ENABLED = false;
public static String getTitleFromObject(Object obj) {
// Fix this result variable to be the correct string.
String result = "";
return result;
}
}

21,518 Pointscan craig help on this one , its no longer learning but confusing, what is the correct answer, what does he want

7,160 PointsThe solution seems to be exactly analog to your example:
Have you tried entering (or copy/pasting) exactly the same as in the example you've given (first code snippet in your post)?

21,518 Pointsi tried many options, all were fruitless,

21,518 Pointswhat would be your answer

7,160 PointsI think we should avoid giving direct solutions, but you wrote that you tried many options, so I guess it's ok now for me to give a possible answer (I hope).
This worked out for me:
import com.example.BlogPost;
public class TypeCastChecker {
/***************
I have provided 2 hints for this challenge.
Change `false` to `true` in one line below, then click the "Check work" button to see the hint.
NOTE: You must set all the hints to false to complete the exercise.

public static boolean HINT_1_ENABLED = false;
public static boolean HINT_2_ENABLED = false;
public static String getTitleFromObject(Object obj) {
// Fix this result variable to be the correct string.
String result = "";
BlogPost bp;
if (obj instanceof String) {
result = (String) obj;
}else if (obj instanceof BlogPost) {
bp = (BlogPost) obj;
result = bp.getTitle();
}
return result;
}
}
Actually it is the very same as in your first code snippet... and I just tried it, and it worked (Task 1 of 2). Not for you?

21,518 Pointstask one was not not a problem, nut thank you so much,
nihouse
7,160 PointsWhy do you write "Challenge Task 1 of 2" on top of your post then? You should have mentioned that your problem is in Task 2 of 2 then
