推荐答案

如果不想将 StringBuilder 转换为 String 或者你需要继续使用它/保存它，然后你可以做这样的事情......

If don't want to convert the StringBuilder to a String or you need to keep using it/preserve it, then you could do something like this...

for (int index = 0; index < sb.length(); index++) {
    if (sb.charAt(index) == '-') {
        sb.setCharAt(index, '/');
    }
}

如果你不在乎那么你可以做点什么喜欢......

If you don't care then you could do something like...

String value = sb.toString().replace("-", "/");
