as3 using addChild with an array containing indexes

so i have an array containing many instances. let's say movieclips.

and i have another array which contains numbers..in this case those numbers represent selected indices that i've somehow chosen!

var manydots:Array = new Array ();

for (var i=0; i<10; i++)
{
    var newDot:dot = new dot  ;
    manydots.push(newDot);
}

var indices:Array = [0,1,5,8,4]

i want to use AddChild to add those movieclips into my scene, but not all of them, only selected indices contained in my 2nd array

sberry solution is correct. But you may also want to check that you actually are not adding null as a child.

for each(var i:int in indices) {
    if (i < manydots.length) {
        var d:dot = manydots[i];
        if (d) {
            addChild(d);
        }
    }
}

I think this is what you are looking for,

for (var j=0; j<indicies.length; j++) {
    addChild(manyDots[incidies[j]]);
}
