Main.java:27: error: -> expected List<Double>Result = newArrayList<Double>(); ^

This error message indicates that there is a syntax error in the code on line 27. The arrow symbol "->" is not expected in this context.

Based on the code snippet provided, it is likely that there is a missing space between "List<Double>" and "Result" in the code. The correct syntax should be:

List<Double> result = new ArrayList<Double>();

Note the space between "List<Double>" and "result". Additionally, the method should be capitalized as "new ArrayList<>()" instead of "newArrayList<>()".
