？replaceAll可以与*，$，%一起使用吗？如果没有，我可以使用replaceAll的其他替代方案吗？

String str = "This is a * string $ with % special characters";
str = str.replaceAll("\\*", "#");
str = str.replaceAll("\\$", "@");
str = str.replaceAll("%", "&");
System.out.println(str);

String str = "This is a * string $ with % special characters";
StringBuilder sb = new StringBuilder(str);
int index = sb.indexOf("*");
while (index != -1) {
    sb.replace(index, index + 1, "#");
    index = sb.indexOf("*", index + 1);
}
index = sb.indexOf("$");
while (index != -1) {
    sb.replace(index, index + 1, "@");
    index = sb.indexOf("$", index + 1);
}
index = sb.indexOf("%");
while (index != -1) {
    sb.replace(index, index + 1, "&");
    index = sb.indexOf("%", index + 1);
}
System.out.println(sb.toString());
