Easiest way to get it by using date pattern - h:mm a, where

最简单的方法是使用日期模式- h:mm a，在哪里。

• h - Hour in am/pm (1-12)
• am/pm h - Hour (1-12)
• m - Minute in hour
• m分钟一分钟。
• a - Am/pm marker
• a - Am / pm标记

Code snippet :

代码片段:

DateFormat dateFormat = new SimpleDateFormat("hh:mm a");

Use this SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm a");

使用此SimpleDateFormat formatDate =新的SimpleDateFormat(“hh:mm a”);

use "hh:mm a" instead of "HH:mm a". Here hh for 12 hour format and HH for 24 hour format.

使用“hh:mm a”而不是“hh:mm a”。这里是12小时格式和24小时格式的hh。

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yy hh.mm.ss.S aa");
String formattedDate = dateFormat.format(new Date()).toString();
System.out.println(formattedDate);

Output: 11-Sep-13 12.25.15.375 PM

输出:11-Sep-13 12.25.15.375点

SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm:ss a");

• h is used for AM/PM times (1-12).

  h用于AM/PM times(1-12)。

• H is used for 24 hour times (1-24).

  H被使用24小时(1-24)。

• a is the AM/PM marker

  a是AM/PM标志。

• m is minute in hour

  m是一分钟一分钟。

Note: Two h's will print a leading zero: 01:13 PM. One h will print without the leading zero: 1:13 PM.

注意:两个h将打印一个前导零:01:13 PM。一个h将会打印，而没有前置零:1:13 PM。

Looks like basically everyone beat me to it already, but I digress

看起来基本上每个人都打我了，但我跑题了。

// hh:mm will print hours in 12hrs clock and mins (e.g. 02:30)
System.out.println(DateTimeFormatter.ofPattern("hh:mm").format(LocalTime.now()));

// HH:mm will print hours in 24hrs clock and mins (e.g. 14:30)
System.out.println(DateTimeFormatter.ofPattern("HH:mm").format(LocalTime.now())); 

// hh:mm a will print hours in 12hrs clock, mins and AM/PM (e.g. 02:30 PM)
System.out.println(DateTimeFormatter.ofPattern("hh:mm a").format(LocalTime.now()));

Using Java 8:

使用Java 8:

LocalTime localTime = LocalTime.now();
DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("hh:mm a");
System.out.println(localTime.format(dateTimeFormatter));

The output is in AM/PM Format.

输出是AM/PM格式。

Sample output:  3:00 PM

Just replace below statement and it will work.

只需替换下面的语句，它就可以工作了。

    //To get Filename + date and time


    SimpleDateFormat f = new SimpleDateFormat("MMM");
    SimpleDateFormat f1 = new SimpleDateFormat("dd");
    SimpleDateFormat f2 = new SimpleDateFormat("a");

    int h;
         if(Calendar.getInstance().get(Calendar.HOUR)==0)
            h=12;
         else
            h=Calendar.getInstance().get(Calendar.HOUR)

    String filename="TestReport"+f1.format(new Date())+f.format(new Date())+h+f2.format(new Date())+".txt";


The Output Like:TestReport27Apr3PM.txt

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm a");

This will display the date and time
