line 155-156 is:
```java
if (sortedCurr.data.equals(curr.data) ||
sortedCurr.data.compareTo(curr.data) > 0)
```
I'll let Chris handle this one.
try changing it to:
```java
if ( (sortedCurr.data.equals(curr.data)) ||
(sortedCurr.data.compareTo(curr.data) > 0) )
```
it still gives an error
What's the error?
"The method compareTo(Object) is undefined for the type Object"
You're missing a (
where?
and why would that make the compareTo method undefined?
before sorted
second line
Doesn't look like it's closed
nah all the parentheses are closed
I changed it to the one Chris sent
I'm not getting any errors from parentheses
@Jacob `data` is an Object, how do you know it implements the Comparable interface?
```java
javac Tester.java
./CDoublyLinkedList.java:155: error: cannot find symbol
(sortedCurr.data.compareTo(curr.data) > 0)) {
^
symbol: method compareTo(Object)
location: variable data of type Object
1 error
```
is there a way I can make it implement comparable class?
I'm not sure how much I'm supposed to modify this assignment
You can try to call the compareTo method and then catch an Exception if compareTo is not implemented
how do I do that?
I feel like there's a better way that I'm missing, since this is part of the assignment and I don't think he wants us to modify the given code
well, besides filling in the methods
maybe I could cast the object?
the tester class only uses characters
@Jacob Cast it as Comparable?
or maybe as a char
or integer if that's possible
I don't know
@Jacob
line 4
```java
private Object data; //Assume data implemented Comparable
```
OK... you can assume that, but Java is going to want that declared somewhere
or it will refuse to compile
I think he really may want you to try/catch
God
I did this stuff like two years ago
I got a Java developer certificate when I graduated high school
