Looks like you shared a lot of code, this may cause people to overlook problems in your code. To make it easier for them, make sure you only share lines that are relevant to your issue.

And it would be great if you specify your problem and not just paste the entire class without comment.

You have another variable "list" defined in the scope. Rename one of them.

Then you have other errors hindering compilation. What other errors does the ide show ?

worldly glen
#

I tried to change a little and it goes fine without errors in lines but when runtime. the error appear

tough coral
#

As I said please only share the relevant part of you code formatted correctly

Please format your code & make it more readable.
For the java programming language, it should look like this:

```java
public class Main{
public static void main(String[] args){
System.out.println("Hello World!");
}
}```
• These are backticks, not quotes.

Enter the initial size of the doubly linked list: 3
Enter the elements of the doubly linked list in ascending order:
123
124
125
Exception in thread "main" java.lang.NegativeArraySizeException: -2147483648
at SkippedList.SkipList.<init>(SkipList.java:39)
at SkippedList.SkipList$DoublyLinkedList$Main.main(SkipList.java:228)

Whats line 39 in SkipList and whats line 228 in DoubleLinkedList

worldly glen
#

that's it

#

The user will input the initial size and elements of the doubly linked list. Only integer
values are valid elements. After the input, all elements must be sorted in ascending order. This
operation must be performed before other operations. This operation can only be performed once.

#

after I input the integer value. it error during runtime

Check what the value of skipSize and levels are in line 39

worldly glen
#

what do you mean value??

#

the inputted integer or variable?

tough coral
#

The value of the two variables I just listed.

worldly glen
#

okay gets. there's no value stored in the variable level and skipList

#

it is needed to inputted by the user

tough coral
#

In line 39 they better have a value. Whats the value both variables have in line 39. Use a debugger to find out

worldly glen
#

#

I only use terminal sir
