How would you create classic instances using this aproach, creating a factory. "Rethinking interfaces"

OperationWithOperationData.java

class OperationWithOperationData {

    Predicate<String>                   isOperation;
    IntBinaryOperator                   reductionOperation;
    List<Integer>                       toOperateOn;

    private OperationWithOperationData() {};
    
    public static Function<
                    List<Integer>,
                    OperationWithOperationData
                    > of(
            Predicate<String>                   isOperation,
            IntBinaryOperator                   reductionOperation

        return toOperateOn ->
            {
                OperationWithOperationData toBuild = new OperationWithOperationData();
