Java:string and date types convert to each other __java

String converted to date type:
Method 1:
Also the simplest method date Date=new date ("2008-04-14");

Method 2:
SimpleDateFormat sdf=new SimpleDateFormat ("Yyyy-mm-dd");/lowercase MM indicates minutes
String dstr= "2008-4-24";
Java.util.Date Date=sdf.parse (DSTR);

Method 3:

public static Date stringtodate (String str) {  
	        dateformat format = new SimpleDateFormat ("Yyyy-mm-dd");  
	        Date date = null;  
	        try {  
	            //Fri Feb 00:00:00 CST  
	            date = Format.parse (str);   
	        } catch (ParseException e) {  
	            e.printstackt Race ();  
	        }  
	        2012-02-24  
	        date = java.sql.Date.valueOf (str);  
	                                              
	        return date;  
	    }  

Date startdate=stringtodate (starttime);

Date converted to string:

SimpleDateFormat sdf=new SimpleDateFormat ("Yyyy-mm-dd");
Java.util.Date date=new java.util.Date ();
String Str=sdf.format (date);
