iwant to optimize the code in the place of switch case

Assuming your objects are known and what you need are simply
variable names created by the program, try using objects as
associative arrays:
var asArray:Object = new Object();
for (var n:int = 0; n < 10; n++) {
asArray["obj" + n] = new WHAT_EVER();
