用单个出现替换字符的多个连续出现

您可以使用此代码段的快速实现。

public static String removeConsecutiveChars(String str) {        if (str == null) { return null;        }        int strLen = str.length();        if (strLen <= 1) { return str;        }        char[] strChar = str.toCharArray();        char temp = strChar[0];        StringBuilder stringBuilder = new StringBuilder(strLen);        for (int i = 1; i < strLen; i++) { char val = strChar[i]; if (val != temp) {     stringBuilder.append(temp);     temp = val; }        }        stringBuilder.append(temp);        return stringBuilder.toString();    }
