sort List by opendate property in bean class

Question

My method is

public FilteredUIExcessList getCustomerExcesses(Long cif,String primaryCO) throws Exception {
    if (cif != null && !cif.equals(0L)) {
        List<CrExcessMaster> crExcessMasterList = getExcessDbService()
                    .getExcessesForCustomer(cif);
}

ExcessUIBean class has opendate property

public class ExcessUIBean implements Comparable<ExcessUIBean>{

    private boolean notifyDaHolder;
    private String daValueForUser;
    private String excessId;
    private String excessDa;
    private String status;
    private String product;
    private String measure;
    private String currency;
    private String limitAtExcess;
    private String excessAmount;
    private String excessDate;
    private String maxRiskAmount;
    private String maxRiskDate;
    private String comments;
    private String preDefinedComments;
    private String openDate;

    public String getOpenDate() {
        return openDate;
    }

    public void setOpenDate(String openDate) {
        this.openDate = openDate;
    }
//getters and setters

I need to sort crExcessMasterList as per opendate property

`ExcessUIBean` should have a `compareTo` method since it is implementing the `Comparable` interface. Could you post this code if it contains something with `openDate`/`getOpenDate()` involved? — cyroxx, May 14 '13 at 12:27

You need to implement Comparable in the class CrExcessMaster .and then override compareTo()

         public int compareTo(CrExcessMaster obj) {
          return   openDate.compareTo(obj.getOpenDate)
         }

and then use Collections.sort(listName);

As from the OP's code, it seems that the `Comparable` interface is already implemented, however, we do not know how. If there is already a `compareTo()` method different from your implementation, the OP probably cannot use your solution without breaking things. – cyroxx May 14 '13 at 12:37
