You can loop through the keys of the allOnlineCarsRealRecordsMap and check if moveId exists in the map using the containsKey method. Here's an example:

for (Long key : allOnlineCarsRealRecordsMap.keySet()) {
    if (key.equals(moveId)) {
        // moveId exists in allOnlineCarsRealRecordsMap
        // do something
        break; // exit the loop if found
    }
}

Alternatively, you can use the containsValue method to check if moveId exists as a value in the map:

if (allOnlineCarsRealRecordsMap.containsValue(moveId)) {
    // moveId exists in allOnlineCarsRealRecordsMap as a value
    // do something
}

Choose the method that suits your requirement
