if I want to make a (Tree)Set and fill开发者_开发技巧 it with 2000 Integers. To start with 0 then add 1,2,3,4...2000. Whats the best way?
I could do
Set set = new TreeSet<Integer>();
set.add(0);
set.add(1);
set.add(2);
//...
or make a while with add(i);i++;
But is there a easier/shorter way?
Thank you!
Not really, there are no bob=[0...2000] shortcuts in Java.
Set set = new TreeSet<Integer>();
for(int i = 0; i <= 2000; ++i)
set.add(i);
Set set = new TreeSet<Integer>();
// add Integers 0,1,...1999
for(int i=0;i<2000;i++){
set.add(new Integer(i));
}
