首先,创建一个格式化程序和一个Calendar对象。
Formatter f = new Formatter(); Calendar c = Calendar.getInstance();
要显示完整的日期和时间信息,请使用'c'转换字符。但是,要以大写形式显示,请使用“ Tc”。
f = new Formatter(); System.out.println(f.format("\nDate and Time (uppercase): %Tc\n", cal));
以下是一个例子-
import java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar cal = Calendar.getInstance(); System.out.println("Current date and time: "+cal.getTime()); f = new Formatter(); System.out.println(f.format("\nDate and Time (uppercase): %Tc\n", cal)); } }
输出结果
Current date and time: Mon Nov 26 07:44:39 UTC 2018 Date and Time (lowercase): MON NOV 26 07:44:39 UTC 2018
