Java相当于.NET的String.Format

看一下String.format和PrintStream.format方法。

两者都基于java.util.Formatter类。

String.format示例：

Calendar c = new GregorianCalendar(1995, MAY, 23);String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY", c);// -> s == "Duke's Birthday: May 23, 1995"

System.out.format示例：

// Writes a formatted string to System.out.System.out.format("Local time: %tT", Calendar.getInstance());// -> "Local time: 13:34:18"
