您的代码有效，但您可以这样写：

Your code works, but you can write something like this:

return Arrays.stream(array)
            .collect(Collector.of(
                          JSONArray::new, //init accumulator
                          JSONArray::put, //processing each element
                          JSONArray::put  //confluence 2 accumulators in parallel execution
                     ));

再来一个例子（从一个 String 创建一个列表< String> ）：

one more example (create a String from List<String>):

List<String> list = ...
String str = this.list
                 .stream()
                 .collect(Collector.of(
                    StringBuilder::new,
                    (b ,s) -> b.append(s),
                    (b1, b2) -> b1.append(b2),
                    StringBuilder::toString   //last action of the accumulator (optional)  
                 ));
