Java将驼峰格式的长字符串转为一句话

    @Test
    public void translateString2Sequence() {
        String regex = "[A-Z]{1}[a-z]{1,}";
        String str = "privatePhilipsReconstructionStorage";
        Matcher matcher = Pattern.compile(regex).matcher(str);

        int position = 0;
        StringBuilder temp = new StringBuilder();
        while (matcher.find()) {
            int start = matcher.start();
            int end = matcher.end();
            String content = matcher.group(0);
            if (position < start) {
                String sub = str.substring(position, start);
                temp.append(sub).append(" ");
            }
            temp.append(content).append(" ");
            position = end;
        }
        if (position < str.length()) {
            temp.append(str.substring(position));
        }
        StringBuilder sequence = new StringBuilder().append(Character.toUpperCase(temp.charAt(0))).append(temp.substring(1));
        System.out.println(sequence.toString().trim());
    }

输出：Private Philips Reconstruction Storage
