Java – sort the vectors of custom objects

How to sort the vectors of custom objects and select the attributes to sort?

I do see this question & answer, but I'm not sure what its ranking is based on Code examples will take precedence over methodology

Sort a Vector of custom objects

public class ItemLocation {
    String icon;
    String title;
    String message;
    String subtext;
    String deviceid;
    double latCoords;
    double lngCoords;
    int expiary;
    int id;
    double proximity;
    String locSeen;
}

Solution

The following is an example that allows you to sort by the specified field of itemlocation:

public void sort(final String field,List<ItemLocation> itemLocationList) {
    Collections.sort(itemLocationList,new Comparator<ItemLocation>() {
        @Override
        public int compare(ItemLocation o1,ItemLocation o2) {
            if(field.equals("icon")) {
                return o1.icon.compareTo(o2.icon);
            } if(field.equals("title")) {
                return o1.title.compareTo(o2.title);
            } else if(field.equals("message")) {
                return o1.message.compareTo(o2.message);
            } 
            .
            . fill in the rest of the fields...
            .
            else if(field.equals("locSeen")) {
                return o1.locSeen.compareTo(o2.locSeen);
            } 
        }           
    });
}
