Question

I ran into an error while making a toString method for a linked list of 'a' to 'z'. The result String returned back to the public method only contains 'a' when the result println shows a-z

public String toString()
{
String result = "{";

result = generateList(result, first);
result += "}";
return result;
}

private String generateList(String result, Node first)
{
result += "," + first.data;
System.out.println(result); //tests what result contains at each iteration
if(first.next != null)
{
generateList(result, first.next);
}
ret

Answer 1

last part is "return result;"

I think the fix to this is to put the return statement of the private method in an else statement, but this results in an error.

Answer 2

It appears result = generateList(); works..
