Talend date and time combine - date

Question

I combine two columns; date and time. When I pass the date and time hot coded it works fine but when I pass it through a column it throws the error:
Unparseable date: "05/05/1992"
I already tried this:
MaterialCodeCSV.xdate == null ?
TalendDate.parseDate("yyyy-MM-dd HH:mm:ss", TalendDate.getDate("yyyy-MM-dd HH:mm:ss")) :
TalendDate.parseDateLocale("yyyy/mm/dd HH:mm:ss",MaterialCodeCSV.xdate.toString() + MaterialCodeCSV.xtime.toString(),"EN");
Java code in Talend:

Date handling can be a bit tricky if using wrong data types. I assume you want to fill a field which is a Date. There are several errors with this way:
MaterialCodeCSV.xdate == null ?
TalendDate.parseDate("yyyy-MM-dd HH:mm:ss", TalendDate.getDate("yyyy-MM-dd HH:mm:ss")) :
TalendDate.parseDateLocale("yyyy/mm/dd H:mm:ss",MaterialCodeCSV.xdate.toString()+ MaterialCodeCSV.xtime.toString(),"EN");
If MaterialCodeCSV.xdate == null you create a date and parse it again instantly? That seems unneccessary complex and inefficient. Change this to TalendDate.getCurrentDate()
Then if xdate is not null, you just concat xdate and xtime, use toString() and try to parse this. Again, this seems unneccesary complex. If I just assume now and xdate and xtime are already Date fields, you could write it as this: MaterialCodeCSV.xdate + MaterialCodeCSV.xtime.
If both are String fields, you have to make sure that xdate is formatted yyyy/MM/dd and xtime is HH:mm:ss. Then you could exclude .toString()
Also, if both are String fields, you have to add an additional space: MaterialCodeCSV.xdate + ' ' + MaterialCodeCSV.xtime
Additionally, in the first case you parse with yyyy-MM-dd HH:mm:ss. In the second case you parse with yyyy/mm/dd H:mm:ss. This reads "year/minute/day". Also there is only one hour digit, not allowing anything after 9:59:59 o'clock to be parsed. Correctly you should use yyyy/MM/dd HH:mm:ss.
So to conclude it should look like this (if I assume correctly and you are using correctly formatted String fields for xdate and xtime):
MaterialCodeCSV.xdate == null ?
TalendDate.getCurrentDate() :
TalendDate.parseDateLocale("yyyy/MM/dd HH:mm:ss", MaterialCodeCSV.xdate + ' ' + MaterialCodeCSV.xtime,"EN");
