如何阻止LinkedHashSet接受区分大小写的值？[闭门]

Question

 String paragraph = "Lalit Kumar Lalit";

 public static void removeDuplicates(String paragraph) {
        char[] charPara;
        charPara = paragraph.toCharArray();
        LinkedHashSet<String> tempPara = new LinkedHashSet<String>();
        for (int i=0; i< charPara.length; i++) {
            tempPara.add(String.valueOf(charPara[i]));
        }
        System.out.println(tempPara);

    }

预期输出：Lait Kumr
实际值：[L，a，L，i，t，K，u，m，r]

Answer 1

也许不是最好的办法但成功了

    public static void removeDuplicates(String paragraph) {
    char[] charPara;
    charPara = paragraph.toCharArray();
    ArrayList<String> tempPara = new ArrayList<>();
    for (int i = 0; i < charPara.length; i++) {
        int finalI = i;
        if (tempPara.stream().noneMatch(x -> x.equalsIgnoreCase(String.valueOf(charPara[finalI]))))
            tempPara.add(String.valueOf(charPara[i]));
    }
    System.out.println(tempPara.stream().collect(Collectors.joining()));

}
