Date type to string and string to date type

The date type is a string and a string date type, which is converted manually in Jsp/servlet and is automatically converted in struts2

SimpleDateFormat is a specific class that formats and resolves dates in a locale-related manner. It allows formatting (date-> text), parsing (text-> date), and normalization

Take a look at the converted code:

Package com.ttgbook.conver;

Import Java.text.DateFormat;
Import Java.text.SimpleDateFormat;
Import java.util.Date;

public class Conver {
	
	//convert date to string public
	static string convertostring (date date)
	{
		DateFormat df = new Sim Pledateformat ("Yyyy-mm-dd");
		
		return Df.format (date);
	Convert string to date public
	static Date convertodate (String strdate) throws Exception
	{
		DateFormat df = new SimpleDateFormat ("Yyyy-mm-dd");
		Return Df.parse (strdate);
	}
     

When a string is converted to a date, an exception is thrown

DateFormat is an abstract class
