Java-8:要流式传输的布尔原始数组?

There is no nice way to convert given boolean[] foo array into stream in Java-8 in one statement, or I am missing something?

(I will not ask why?, but it is really incomprehensible: why not add stream support for all primitive types?)

Hint: Arrays.stream(foo) will not work, there is no such method for boolean[] type.

解决方案

Given boolean[] foo use

Stream<Boolean> stream = IntStream.range(0, foo.length)
                                  .mapToObj(idx -> foo[idx]);

Note that every boolean value will be boxed, but it's usually not a big problem as boxing for boolean does not allocate additional memory (just uses one of predefined values - Boolean.TRUE or Boolean.FALSE).
