Java is shaped like yyyy-mm-dd ' T ' HH:mm:ss. The problem of SSSZ into various formats

Yyyy-mm-dd ' T ' HH:mm:ss. Sssz

The following three SSS refer to milliseconds, Z represents the time zone, and the middle T represents any replaceable character.

Here's a look at the example:
Example One:

@Test public
    void Testtime () throws parseexception{
       Date date = new Date (); 
       SimpleDateFormat df = new SimpleDateFormat ("Yyyy-mm-dd ' T ' HH:mm:ss. Sssz ");
       SimpleDateFormat df1 = new SimpleDateFormat ("Yyyy-mm-dd ' Test" HH:mm:ss.) Sssz "); 
       String str = df.format (date);
       String str1 = Df1.format (date);     
       System.out.println (str);
       System.out.println (STR1);     
    }

Test results

2017-06-08t10:41:06.261+0800
2017-06-08 Test 10:41:06.261+0800

Example Two:

Convert 2017-05-18t10:26:10.488z to YYYY-MM-DD HH:mm:ss or YYYYMMDDHHMMSS format

@Test public
    void TestTime1 () throws parseexception{
       String datestr = "2017-05-18t10:26:10.488z";
       SimpleDateFormat DFF = new SimpleDateFormat ("Yyyy-mm-dd ' T ' HH:mm:ss.") SSS ", Locale.english)//converted time format of input
       SimpleDateFormat df1 = new SimpleDateFormat (" Yyyy-mm-dd HH:mm:ss "); The time format needed to be converted
       SimpleDateFormat df2 = new SimpleDateFormat ("Yyyymmddhhmmss");
       Date date1 = Dff.parse (DATESTR);     
       String str1 = Df1.format (date1);
       String str2 = Df2.format (date1);
       System.out.println ("str1 is" +str1);
       System.out.println ("str2 is" +str2);
    }

Run Result:

STR1 is 2017-05-18 10:26:10
str2 is 20170518102610

All of the above are Pro test: Fair trade.
