java - 如何从字符数组中删除特定位置的特定字符？

Question

我需要从字符数组中删除一个字符并重新调整数组的大小。到目前为止，我一直致力于用特殊字符替换特定字符。

在此代码中，我正在搜索找到的任何匹配项，即，如果有任何字符在男性和女性字符数组中匹配，并且如果找到我将其替换为“*”。取而代之的是，我必须删除该字符并调整数组的大小。

private static void Compare(String Male,String Female) {

    char[] male;
    char[] female;
    // converting a string into charecter array

    male=Male.toCharArray();
    female=Female.toCharArray();

    //finding any matches i.e, any charecter is matching or not 
    for(int i=0;i<male.length;i++){

        for(int j=0;j<female.length;j++)
        {
            String m = Character.toString(male[i]);
            String fm = Character.toString(female[j]);
            if(m.equals(fm)){
            //if the charecters are equal  then  replacing them with "*"    

                male[i]='*';
                female[j]='*';

            }
        }
    }

试试这个:

    String male = "maleg*$m-z";
    String female= "femal^\\$e-is";
    String deletedMale = male.replaceAll("["+Pattern.quote(female)+"]", "");
    String deletedFemale = female.replaceAll("["+Pattern.quote(male)+"]", "");
    System.out.println(deletedMale);
    System.out.println(deletedFemale);
