sort jtree

[mark goking]

i successfully sorted my jtree alphabetically by implementing comparable in the defaultmutabletreenode but i am having a problem with a restriction in the 1st level.

if the node is labeld "CAR" it should always stop at the top (1st node) and if the label is HOUSE it should always stay as the last node of the first level nodes. the rest of the nodes will be sorted alphabetically.

how to do this within the compare() method in a short way. thanks.

currently it works if i manually do if statements if the label is CAR or HOUSE and check what the value of the compare method is. im looking for a simplified way if there is. thanks

But that's what you said the rule was. I don't see how the implementation can be simpler than the rule.

I am a bit confused.
Do you mean to say first level nodes under root should not be sorted, but their children should be?

Root
    Car <----1st level node. Do NOT compare with House and sort
        Ferrari <--- All children of Car should be sorted?
        Lamborghini
        Honda
    House
        Ranch
        Mansion
        Palace

hi maneesh.
1st level nodes should be sorted, but if the string is CAR, it should always be the first node. if it is HOUSE is should always be the last node.

e.g.

root
-CAR
-- child1
-- child2
-AIRCRAFT
-- child1
-- child2
-BUILDING
-- child1
-- child2
-HOUSE
-- child1
-- child2

aircraft and building are sorted. while car and house are not. car should always be the first and house should always be the last

for the moment, this is how i did it

protected Comparator nodeComparator = new Comparator () {

int output = o1.toString().compareToIgnoreCase(o2.toString());
                if (o1.toString().equalsIgnoreCase("CAR")) {
                    if (output > 0) output = -Math.abs(output);
                } else if (o2.toString().equalsIgnoreCase("CAR")) {
                    if (output < 0) output = Math.abs(output);
                } else if (o1.toString().equalsIgnoreCase("HOUSE")) {
                    if (output < 0) output = Math.abs(output);
                } else if (o2.toString().equalsIgnoreCase("HOUSE")) {
                    if (output > 0) output = -output;
                }
return output;
}

just wondrin' if there's a simplier way to simplify it ;)
