怎樣創(chuàng)建integer類型的數(shù)組？

//將int數(shù)組轉(zhuǎn)換為Integer數(shù)組

int[] nums = {1,2,3,4};

//先將int數(shù)組轉(zhuǎn)換為數(shù)值流

Stream stream = Arrays.stream(nums);

//流中的元素全部裝箱，轉(zhuǎn)換為流

//-->int轉(zhuǎn)為Integer

Stream integerStream = stream.boxed();

//將流轉(zhuǎn)換為數(shù)組

Integer[] integers = integerStream.toArray(Integer[]::new);

System.out.println(Arrays.toString(integers));
