How to create dynamic Seq in java

Question

I want to create a Dataset out of another one but only with some specific columns and I would like to use the `dataset.select()` function instead of creating a dynamic sql query who select from this dataset the columns I need. I have found that using `JavaConversions.asScalaBuffer(asList(new Column("value1"), new Column("value2")))` I can create a `Set` but how can I do it dynamic? because I've tried this. ``` List filterColumns = new ArrayList<>(); for (ColumnMetadata field : fields) { filterColumns.add(new Column(field.getFieldName())); } dataset.select(JavaConversions.asScalaBuffer(asList(filterColumns))) ``` But this doesn't work and the compiler said `no suitable method found for select(Buffer>)`

Accepted Answer

Use it like below with list.

```
dataset.select(JavaConversions.asScalaBuffer(filterColumns));
```

or like this with seq.

```
dataset.select(JavaConversions.asScalaBuffer(filterColumns).seq());
```
