Is there any method in Java to init a set by step 1 or other length? -

for example, init set [1,2,3, ...,100].

usually, follows:

for(int = 1;i <= 100;i++ ){     set.add(i); }

is there method more conveniently?

such somemethod(startindex, endindex, step);

by using that, can init set [1,2,3,4,5] or [1,3,5,7,9] or others.

you can use java 8 streams.

for example :

set<integer> myset = intstream.range(1,101).boxed().collect(collectors.toset());

or odd numbers :

set<integer> myset = intstream.range(1,101).filter(i->i%2==1).boxed().collect(collectors.toset());
