java从字符串中删除指定字符

public static String delChar(String rSu, char cl) {
		StringBuffer sBuff = new StringBuffer();
		int bEnd = 0;
		int len = rSu.length();
		if (len == 1) {
			sBuff.append(rSu);
			return sBuff.toString();
		}
		for (int i = 0; i < len; i++) {
			bEnd = rSu.indexOf(cl, 0);
			if (bEnd != -1) {
				sBuff.append(rSu.substring(0, bEnd));
				rSu = rSu.substring(bEnd + 1);
				if (rSu.length() == 1) {
					if (rSu.indexOf(cl, 0) == -1) {
						sBuff.append(rSu);
						break;
					} else {
						break;
					}
				}
			}
		}
		return sBuff.toString();
