Combine guava's ImmutableList and varargs
- by Stas Kurilin
I want create constructor that will take one or more integers and save it into field as ImmutableList. According to "The right way to use varargs to pass one or more arguments" by Bloch's Item 42 I create smt like
class Foo{
private final ImmutableList<Integer> bar;
public Foo(Integer first, Integer... other) {
this.bar = ImmutableList.<Integer>builder()
.add(first)
.addAll(Arrays.asList(other))
.build();
}
}
Why builder doesn't get generic automatically? And, as it smells. How I can rewrite it?
