首先,创建一个Formatter和一个Calendar对象。
Formatter f = new Formatter(); Calendar c = Calendar.getInstance();
要使用Formatter类显示小时,请使用'l'转换字符-
f = new Formatter(); System.out.println(f.format("Hour: %tl", c));
要使用Formatter类显示分钟,请使用'M'转换字符-
f = new Formatter(); System.out.println(f.format("Minute: %1$tM", c));
以下是一个例子-
import java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar c = Calendar.getInstance(); System.out.println("Current date and time: "+c.getTime()); f = new Formatter(); System.out.println(f.format("Hour and Minute with AM/ PM: %tl:%1$tM %1$Tp", c)); f = new Formatter(); System.out.println(f.format("Hour: %tl", c)); f = new Formatter(); System.out.println(f.format("Minute: %1$tM", c)); } }
输出结果
Current date and time: Mon Nov 26 07:35:43 UTC 2018 Hour and Minute with AM/ PM: 7:35 AM Hour: 7 Minute: 35
