How do i convert 24 hours format to 12 hours along with AM/PM, i have checked articles and also in stackoverflow but problem is if string is "12:43" (afternoon time) and i converted it into 12 hours then it shows "12:43 AM" but it should show "12:43 PM". Below is the java code which i have written.
> MainActivity.Java
public class PrayerActivity extends AppCompatActivity {
TextView result;
String fetch="12:43"
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
result=findViewById(R.id.result);
Date dateCode = null;
String formatTwelve;
String resultsAfter;
final SimpleDateFormat code12Hours = new SimpleDateFormat("hh:mm");
try {
dateCode = code12Hours.parse(fetch);
} catch (ParseException e) {
e.printStackTrace();
}
formatTwelve = code12Hours.format(dateCode);
if (formatTwelve.equals(fetch)) {
resultsAfter= formatTwelve + " AM";
} else {
resultsAfter= formatTwelve + " PM";
}
result.setText(resultsAfter);
}}

public static void main(String[] args) {
String[] stringDates = { "12:43", "14:00", "10:00" };
for (String dateString : stringDates) {
// Input 24 HRS
LocalTime localTime = LocalTime.parse(dateString, DateTimeFormatter.ofPattern("HH:mm", Locale.ENGLISH));
// Output 12 hrs
System.out.println(localTime.format(DateTimeFormatter.ofPattern("hh:mm a", Locale.ENGLISH)));
}
}
output
12:43 PM
02:00 PM

以下是翻译好的部分：
你只需要使用 "h:mm a" 或 "hh:mm aa" 来获取更多细节或者代码，你可以参考这个 gist 链接以便更好地理解。
try {
String timeLong = "2020-10-08 06:06:30";
String timeShort = "16:06 AM";
SimpleDateFormat formatLong = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US);
SimpleDateFormat formatShort = new SimpleDateFormat("hh:mm aa", Locale.US);
Log.v("out", formatShort.format(formatLong.parse(timeLong)));
Log.v("out", formatShort.format(formatShort.parse(timeShort)));
} catch (ParseException e) {
e.printStackTrace();
}
输出：
06:06 AM
04:06 PM
