java占位符像C#{0}那样简单

import java.text.MessageFormat;

System.out.println(MessageFormat.format("start={0}, end={1} ", "22222", "333333"));


public static String joinXmlElement(String element, String value) {
		return MessageFormat.format("<{0}>{1}</{0}>\n", element, value);
	}

	public static void main(String[] args) {
		System.out.println(joinXmlElement("msg", "我爱你"));
	}

输出：<msg>我爱你</msg>
