package com.pr.trio;
import java.util.Arrays;
public class kk {
    public static void main(String[] args) {
        lalala l1 = new lalala();
        //currently passed as an empty array, want to set SegmentationFieldId & value here from inner class
        l1.setSegmentationFieldValues(Arrays.asList());  
        //lalala.SegmentationFieldValue.this.setSegmentationFieldId(15);
        System.out.println(l1.getSegmentationFieldValues());
}
}

所以在这里，我不能为segmentation字段而不是空数组传递值，这是一个错误。那么如何设置内部类字段的值并将其传递到我的列表中呢？
