list分组填充数据

Question

如何将数据分组填充。

将下面的"李健康","张健全"添加到第一组，将"杨无灾","张无难"添加到第二组

    private List<BaseNode> getEntity1() {
        String [] secondNodeList1 =new String[] {"一组","二组","三组","四组","五组","六组"};
        String [][] FirstNode1 = new String[][]{{"李健康","张健全"},{"杨无灾","张无难"},
                {"杨定云","陈定雨"},{"曾阿牛","普阿猫"},{"赵贵人","高才人"},
                {"何必","任性"}};
        List<BaseNode> list = new ArrayList<>();
        for (int i = 0; i < secondNodeList1.length; i++) {
            List<BaseNode> secondNodeList = new ArrayList<>();
            for (int n = 0; n <= FirstNode1[n].length; n++) {
                SecondNode seNode = new SecondNode(secondNodeList, ""+FirstNode1[0][0]);
                secondNodeList.add(seNode);
            }
            FirstNode entity = new FirstNode(secondNodeList, secondNodeList1[i]);
            list.add(entity);
        }
        return list;
    }

FirstNode 类

public class FirstNode  extends BaseExpandNode {
    private List<BaseNode> childNode;
    private String title;

    public FirstNode(List<BaseNode> childNode, String title) {
        this.childNode = childNode;
        this.title = title;

        setExpanded(false);
    }

    public String getTitle() {
        return title;
    }


    @Nullable
    @Override
    public List<BaseNode> getChildNode() {
        return childNode;
    }
}

SecondNode 类

public class SecondNode extends BaseExpandNode {

    private List<BaseNode> childNode;
    private String title;

    public SecondNode(List<BaseNode> childNode, String title) {
        this.childNode = childNode;
        this.title = title;

        setExpanded(false);
    }

    public String getTitle() {
        return title;
    }

    @Nullable
    @Override
    public List<BaseNode> getChildNode() {
        return childNode;
    }
}

private List<BaseNode> getEntity1() {
    String[] secondNodeList1 = new String[] {"一组", "二组", "三组", "四组", "五组", "六组"};
    String[][] firstNode1 = new String[][]{{"李健康", "张健全"}, {"杨无灾", "张无难"},
            {"杨定云", "陈定雨"}, {"曾阿牛", "普阿猫"}, {"赵贵人", "高才人"}, {"何必", "任性"}};
    List<BaseNode> list = new ArrayList<>();
    for (int i = 0; i < secondNodeList1.length; i++) {
        List<BaseNode> secondNodeList = new ArrayList<>();
        for (int j = 0; j < firstNode1.length; j++) {
            // 如果当前数据需要添加到当前组中
            if (secondNodeList1[i].equals("一组") && (firstNode1[j][0].equals("李健康") || firstNode1[j][0].equals("张健全"))
                    || secondNodeList1[i].equals("二组") && (firstNode1[j][0].equals("杨无灾") || firstNode1[j][0].equals("张无难"))) {
                SecondNode seNode = new SecondNode(null, firstNode1[j][0]);
                secondNodeList.add(seNode);
            }
        }
        FirstNode entity = new FirstNode(secondNodeList, secondNodeList1[i]);
        list.add(entity);
    }
    return list;
}
