Get string from jsonArray java android Studio

Issue

{
    "resource": [{
        "devid": "862057040386432",
        " time": "2021-11-02 12:36:30",
        "etype": "G_PING",
        "engine": "OFF",
        "lat": "9.235940",
        "lon": "78.760240",
        "vbat": "3944",
        "speed":"7.49",
        "plnt": "10",

        "fuel": 0
    }]
}

I have access to the "resource" JSON Array at this point, but am unsure as to how I'd get the "lat" and "lon" values within a for loop. Sorry if this description isn't too clear, I'm a bit new to programming.

Solution

const data = {
    resource: [{
        devid: "862057040386432",
        time: "2021-11-02 12:36:30",
        etype: "G_PING",
        engine: "OFF",
        lat: "9.235940",
        lon: "78.760240",
        vbat: "3944",
        speed:"7.49",
        plnt: "10",
        fuel: 0
    }
    ]
  };
  
  const latAndLongVersionOne = data.resource.map(res => [res.lat, res.lon]);
  const latAndLongVersionTwo = data.resource.map(({lat, lon}) => [lat, lon]);
  const latAndLongVersionThree = data.resource.map(({lat, lon}) => ({lat, lon}));

  console.log('Lat and long: ', latAndLongVersionOne); // Nested array with long and lat (values names has to be inferred)
  console.log('Lat and long: ', latAndLongVersionTwo); // Same result with another syntax
  console.log('Lat and long: ', latAndLongVersionThree); // Array of objects with caption
