Delegate the compareTo to Strings implementation:



public int compareTo(Object o) {
...
return this.getText().compareTo(o.getText());

  • Regarding sorting of objects

    for sorting with 2 criterias, you will have to first sort by one criteria and then within each "element" do a second sort with the other criteria.

    sort1: 1, 2, 3 ... n
    sort2 1: a, b, c ..., z
    sort2 2: a, b, c ..., z
    sort2 3: a, b, c ..., z
    sort2 ...: a, b, c ..., z
    sort2 n: a, b, c ..., z

    Easy...
