Why This Extension is not Compiling?

[Kumaraswamy]

There are arrays and not list.

[Alpha2020]

I didnt understand

[Kumaraswamy]

Take a look here:

Difference between List and Array

[Alpha2020]

item = (get[index]);

Should we use like this.

[Kumaraswamy]

Use like this:

String item = (String) list.get(INDEX);

Yess it can be!!

[Alpha2020]

I have edited the code. See above

[HIFI_APPS]

@Kumaraswamy

INDEX

Is starts from 0 not 1

[oseamiya]

Anyone know how to fix this import in intelliij IDE??

[Salman_Dev]

@HIFI_APPS

Is starts from 0 not 1

it start from 1

[oseamiya]

@Salman_Dev

it start from 1

I think lndex starts from 0 and position starts from 1? isnt it??

[Salman_Dev]

@oseamiya

I think lndex starts from 0 and position starts from 1? isnt it??

actually the index starts at 0, but the YailList AI index starts at 1, so the code above won't be able to retrieve data starting at index 0

@Salman_Dev

ctually the index starts at 0, but the index in YailList AI starts at 1, so the code above won't be able to retrieve data starting at index 0

YAILIST starts from 1 because there is already presence of a element in index 0. Am I right?

@ewpatton

Edit: It's important to note that YailList internally is implemented as a linked list structure, not as an array. Furthermore, the first element in the list is always the Scheme symbol *list* , which makes the 1-based indexing work. These two facts together are what makes the shortcut in the previous paragraph work because you're modifying the first pair, (*list* ...) by setting its second pointer to the same as your copied list.

yeah you are right

[Salman_Dev]

I think this code starts from 1 because it belongs to the YailList class

@Kumaraswamy

Use like this:

String item = (String) list.get(INDEX);

[AkshatRana]

Can you share the full screenshot

[Salman_Dev]

it will start at 0 I think

That's right.
Better will be to convert YailList into Array to avoid future misconceptions:

String[] arr = list.toStringArray();
String value = arr[index - 1]; //you take AI2 version of index but then convert that to Java's version

@oseamiya Is your Problem fixed now ???
