我们可以使用多个HashMap对结果集进行分组吗

// 创建多个HashMap对象
HashMap<String, List<Data>> group1 = new HashMap<>();
HashMap<String, List<Data>> group2 = new HashMap<>();

// 遍历结果集
for (Data data : resultSet) {
    // 根据条件进行分组
    if (data.getCondition1()) {
        if (!group1.containsKey(data.getKey())) {
            group1.put(data.getKey(), new ArrayList<>());
        }
        group1.get(data.getKey()).add(data);
    } else {
        if (!group2.containsKey(data.getKey())) {
            group2.put(data.getKey(), new ArrayList<>());
        }
        group2.get(data.getKey()).add(data);
    }
}

// 输出结果
System.out.println("Group 1:");
for (String key : group1.keySet()) {
    System.out.println("Key: " + key);
    System.out.println("Data: " + group1.get(key));
}

System.out.println("Group 2:");
for (String key : group2.keySet()) {
    System.out.println("Key: " + key);
    System.out.println("Data: " + group2.get(key));
}
