Answer 1

您需要使用 MessageFormat 并附加您想要创建消息的参数..

示例：

public static void main(String[] args) {

    String msgRaw = "Alibaba {0} {1} site {2} China";
    String[] appender = { "is the best", "online comparison shopping", "in" };
    String text = MessageFormat.format(msgRaw, appender);
    System.out.println(text);
}

输出

Alibaba is the best online comparison shopping site in China

Answer 2

您可以像这样使用 MessageFormat

public static void main(String args[]) throws Exception{
    String result = MessageFormat.format("{0} is {4} online {3} shopping {1} in {2}" ,
            "Alibaba" ,"site",  "china", "comparison", "best");
    System.out.println(result);
}

它会输出

Alibaba is best online comparison shopping site in china
