[FIXED] How to eliminate "The expression of type List needs unchecked conversion to conform " warning?

Issue

The warning is

Type safety: The expression of type List needs unchecked conversion to conform to Collection<? extends String>

Do I need a type cast somewhere?

public class ETLStepType {
    public static final ArrayList<String> ETLStepTypes = ( 
            new ArrayList<String> ((Arrays.asList(new String[] {"constant", 
                                                          "append", 
                                                          "insertupdate", 
                                                          "tableinput",
                                                          "filterrows",
                                                          "dblookup",
                                                          "selectvalues"}))));

}

Solution

in Intellij Idea getting "Redundant array creation for calling varargs method" warning, which fixed by removing 'new String []{ and }' so try

        new ArrayList<String>(Arrays.asList("constant",
                "append",
                "insertupdate",
                "tableinput",
                "filterrows",
                "dblookup",
                "selectvalues"))

to fix the issue
