在 Java 中使用 Formatter 顯示完整日期和時間資訊
首先,建立一個 Formatter 和 Calendar 物件。
Formatter f = new Formatter(); Calendar cal = Calendar.getInstance();
現在顯示當前日期和時間。我們在此以小寫和大寫顯示日期 −
f = new Formatter(); System.out.println(f.format("
Date and Time (lowercase): %tc
", cal)); f = new Formatter(); System.out.println(f.format("Date and Time (uppercase): %Tc
", cal));
以下是一個示例 −
示例
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("
Date and Time (lowercase): %tc
", cal)); f = new Formatter(); System.out.println(f.format("Date and Time (uppercase): %Tc
", cal)); } }
輸出
Current date and time: Mon Nov 26 07:24:21 UTC 2018 Date and Time (lowercase): Mon Nov 26 07:24:21 UTC 2018 Date and Time (uppercase): MON NOV 26 07:24:21 UTC 2018
