java根据行号从数组列表中获取JSON对象

Question

我正在用intellij idea进行开发。这里我的要求是在编辑器中打开一个json文件，并且我的光标位于特定的行上。我能够找到行号，现在我的下一个任务是，从json文件（它是一个对象数组）中获取整个对象，我的光标就在这里。例如，这是我的json

[{
        "facility": "Global",
        "group_names": [
            "H R"
        ],
        "group_type": "department",
        "remove_users_on_logout": false,
        "shift_membership": {
            "min": 50,
            "max": 50,
            "source": "any_shift",
            "type": [
                "auxiliary"
            ]
        },
        "child_members": [{
            "diamond": {
                "diamond_id": "akron_hr"
            }
        }]
    },
    {
        "facility": "Global",
        "group_names": [
            "I T"
        ],
        "group_type": "department",
        "remove_users_on_logout": false,
        "shift_membership": {
            "min": 40,
            "max": 40,
            "source": "per_shift",
            "type": [
                "auxiliary"
            ]
        },
        "child_members": [{
                "diamond": {
                    "diamond_id": "akron_it"
                }
            },
            {
                "diamond": {
                    "diamond_id": "baltimore_it"
                }
            }
        ]
    }
]

例如，如果我在从1到21的任何一行上，我的输出应该是

{
        "facility": "Global",
        "group_names": [
            "H R"
        ],
        "group_type": "department",
        "remove_users_on_logout": false,
        "shift_membership": {
            "min": 50,
            "max": 50,
            "source": "any_shift",
            "type": [
                "auxiliary"
            ]
        },
        "child_members": [{
            "diamond": {
                "diamond_id": "akron_hr"
            }
        }]
    }

谁能告诉我什么方法可以帮助我？谢谢你的帮助。谢谢
