Hi, I have a big enum class(classA) which has more than 2000 constants. And
this been used in a big switch statement.
The project took 40 seconds to run on my eclipse, but it only took 10 second on netbeans. If I change the enum to integer, the problem will gone.
I would like to understand why switch enum on eclipse take this long time.
Any thoughts? Thanks a lot.

Yes, she is one of my colleague.
Is there a method in Eclipse that I can specify the compiler to use? like javac?
The code is very big, but I can give you an example:
public Enum TempType(){
IDA,IDB,IDC...
}
TempType include more than 2300 enum items defined.
And in other class, there is the switch like:
public class TempTypeB(OtherType outerSwitch, TempType ttName){
switch(oterSwitch):
case aaa:
{
switch (ttName):
case IDA:
//do something;
break;
case IDB:
// do something
break;
...
}
...
}
}
The code is very straight forward, it is a double switch, the out side is other type, the inside is enum type. We try to understand why eclipse is much slower than netbeans.
Thanks.
