Not able to create List of String object in java12

List<Object> al = Arrays.asList("ABC", "XYZ");

First, we need to check whether the value of setValues is a list or nested list

ValueRange body=new ValueRange().setValues(Arrays.asList(Arrays.asList("ABC", "XYZ"))); the above will give the results [[ABC, XYZ]] -> Nested array

Instead, try like this

ValueRange body=new ValueRange().setValues(new ArrayList<>(Arrays.asList("ABC", "XYZ")));

This gives results - > [ABC, XYZ]
