java如何给值做转换

Question

取到json对象的area值后，这个value数组的下标为[0]的值前面加x，数组为的下标为[1]的值前面加y

如

    "point": [
        {
            "x": area[0],
            "y": area[1]
        },
        {
            "x": area[0],
            "y": area[1]
        },
        {
            "x": area[0],
            "y": area[1]
        },
        {
             "x": area[0],
            "y": area[1]
        }
    ]
    
     "point": [
        {
            "x": "0.2",
            "y": "0.2"
        },
        {
            "x": "0.5",
            "y": "0.2"
        },
        {
            "x": "0.5",
            "y": "0.5"
        },
        {
             "x": "0.2",
            "y": "0.5"
        }
    ]

   "Protection": [{
        "area": [
            [
                0.2,
                0.2
            ],
            [
                0.5,
                0.2
            ],
            [
                0.5,
                0.5
            ],
            [
                0.2,
                0.5
            ]
        ],
        "Sectionnumber": 1
    },
        {
            "area": [
                [
                    0.2,
                    0.2
                ],
                [
                    0.5,
                    0.2
                ],
                [
                    0.5,
                    0.5
                ],
                [
                    0.2,
                    0.5
                ]
            ],
            "Sectionnumber": 3
        }
    ]
