Java如何优雅实现数组切片和拼接操作

List<String> linesList = Arrays.stream(content.split("\n")).collect(Collectors.toList());

String line = String.join("", linesList.subList(index1, index2));

		int[] originalArray = {1, 2, 3, 4, 5, 6};
        int start = 1; // 起始索引（包含）
        int end = 4;   // 结束索引（不包含）

        // 使用 Arrays.copyOfRange() 进行切片
        int[] slicedArray = Arrays.copyOfRange(originalArray, start, end);

        // slicedArray 现在等于 {2, 3, 4}
        System.out.println(Arrays.toString(slicedArray));

		Integer[] array1 = {1, 2, 3, 4, 5};
        Integer[] array2 = {6, 7, 8, 9, 10};

        // 定义切片范围
        int start1 = 1;
        int end1 = 3;
        int start2 = 2;
        int end2 = 4;

        // 对数组进行切片
        Integer[] slice1 = Arrays.copyOfRange(array1, start1, end1);
        Integer[] slice2 = Arrays.copyOfRange(array2, start2, end2);

        // 使用 Stream API 进行拼接
        Object[] array = Stream.concat(Arrays.stream(slice1), Arrays.stream(slice2))
                .toArray();

        // result 现在等于 {2, 3, 8, 9}
        Arrays.stream(array).forEach(System.out::println);

String[] nameArr = StringUtils.tokenizeToStringArray(nameAttr, MULTI_VALUE_ATTRIBUTE_DELIMITERS);  // nameAttr="made,in;china,;qqq,.aaa" ,MULTI_VALUE_ATTRIBUTE_DELIMITERS=",;."

}

Stream<String> stream = Arrays.stream(nameArr);

String result = stream.collect(Collectors.joining("/", "[", "]"));
System.out.println(result);
// 输出字符串 [made/in/china]
