public class Test {
public static void main(String[] args) {
String url = "我叫%s,今年%s岁。";
String name = "小明";
String age = "28";
url = String.format(url,name,age);
System.out.println(url);
}
}
public class Test {
public static void main(String[] args) {
String url02 = "我叫{0},今年{1}岁。";
String name = "小明";
String age = "28";
url02 = MessageFormat.format(url02,name,age);
System.out.println(url02);
}
}
控制台同样输出：
我叫小明，今年28岁。
