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
or is there a better way to do insertion sort?
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
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
and we did try catch and everything
```java
try {
your code;
}
catch Exception {
//leave empty lol
}
```
we also did Linked Lists I think
put that inside the method?
the entire method? @ThisIsChris
I'd put the `try` at line 148, just before the while loop, don't want that thing to go on catching exceptions forever waiting for the loop to break
so put the entire loop inside it?
so
```java
try {
//lines 149-163, the whole outer while loop, until just before the function ends
}
catch Exception {
//leave blank because we're supposed to assume nothing will happen
}
//then exit the function
}
``` @Jacob
thanks
okay now I have a new exception
here is my new code
