先说这个论坛的ＢＵＧ吧，我那个帖子回复不了了，每次回复都说这个帖子已经发布过一次了，真奇怪

  public static String replaceSubString(
    String parent,
    String oldSub,
    String newSub)
  {
    int sp = 0;
    int ep = 0;

    for (int i = 0; i < parent.length(); i++)
    {
      if (parent.regionMatches(i, oldSub, 0, oldSub.length()))
      {
        sp = i;
        ep = i + oldSub.length();
        break;
      }
    }

    StringBuffer sbParent = new StringBuffer(parent);
    sbParent.replace(sp, ep, newSub);

    return sbParent.toString();
  }

Posted by: Jove Posted on: 2003-04-19 13:49 关于那个Bug,好像你改一下标题就可以了替换String某一部分,可以用 String replace(char oldChar, char newChar) String replaceAll(String regex, String replacement) String replaceFirst(String regex, String replacement) 后两个方法需要j2sdk1.4支持,详见api doc
