Convert Comparable object to string or char

[ScKaSx]

Hi All,

I have a Link List of comparables that I would like to convert into one string:

I am doing something like:

char[] LinkedListArray = null;
int i = 0;

while (not_end_of_linked_list) {
     LinkedListArray[i] = item;
     i++;
     next_in_LinkedList();
}

where item is a comparable that I would like to convert to a string or char. What is the best way to do this?

Cheers,
ScKaSx

Please tell us what you are trying to accomplish. Your code takes each object and reduces it to a single char, which you place in an array. Not to mention you never actually created the array.

Are you wanting the save the state, or all the properties, of each object?

I have no idea what you're trying to accomplish with this, but you can certainly add a toString method to your Comparable implementation.

Basically I have a linked list of comparable objects that I want to concatenate together in a string. For instance, the linked list might look like:

comparable: Adam
|
v
comparable: Mike
|
v
comparble: Tom

I am looping through the linked list and for each comparable item I want to concatenate the comparable into a string so that *.toString() will give:

Adam
Mike
Tom

Any ideas on the correct implementation?

My original code has changed to one using concatenation of a String class:

String LLstring = "";
Comparable item;
 
while (not_end_of_linked_list) {
     LLstring = LLstring + item;
     next_in_LinkedList();
}

However, this doesn't print out the elements of the linked list.

you might need to call toString() explicitly on the item in the loop:

   LLstring += item.toString(); // + "\n"; ???

Also, if you're doing a lot of these concatenations, then use a StringBuilder and call its append(...) method.
