String to Date to String to Date Conversion code

// Fetch current date :

Calender calender = Calender.getInstance();

Date currentDate = calender.getTime();

// Printing  current date in terminal :

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

System.setProperty("current_time", dateFormat.format(new Date()));

// Converting String to Date to String to Date

String endDate = "20200728";

Date date1 = new SimpleDateFormat("yyyyMMdd").parse(endDate);

SimpleDateFormat newFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss z");

String str = newFormat.format(date1);

Date date2 = newFormat(str);

Java String to Date Example :

String sDate1="10/03/1994";  

Date date1=new SimpleDateFormat("dd/MM/yyyy").parse(sDate1);  

System.out.println(sDate1+"\t"+date1);

Java Date to String Example :

Date date = Calendar.getInstance().getTime();  

DateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd hh:mm:ss");  

String strDate = dateFormat.format(date);  

System.out.println("Before conversion of date into String: " + date); 

System.out.println("After conversion of date into String: " + strDate); 

// Inserting user data into EMP table

Connection connection = Platform.getConnection();

pstmt.setString(3, reason);

pstmt.setDate(4, new java.sql.Date(date2.getTime));

pstmt.exceuteUpdate();

connection.commit();
