Your question is vague and ambiguous. I’ll leave the timezone ambiguity away.

How can I convert time in unix timestamp to normal time?

I suspect that you’re somehow obtaining a long or maybe a String value from the DB instead of a Date. In JDBC, you would normally like to use the appropriate methods to obtain the DB-specific datatypes. The MySQL TIMESTAMP datatype can be obtained by ResultSet#getTimestamp() which gives you a java.sql.Timestamp which in turn is a subclass of java.util.Date.

In a nut, the following should do:

Date date = resultSet.getTimestamp("columnname");

To format it further in a human readable format whenever you’re going to present it to the enduser, use SimpleDateFormat. Click the link, it contains an overview of all patterns. Here’s an example:

String dateString = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(date);

To do all the other way round, use respectively SimpleDateFormat#parse() and PreparedStatement#setTimestamp().
