I got the answer,if anyone else is wondering how to do it.

If you have Java 8 &above you can use this routine

Input Date Format should be 'YYYY-MM-dd'

and date column should be passed as a string,you would also get the output as a string

package routines;

import java.time.*;

* user specification: the function's comment should contain keys as follows: 1. write about the function's comment.but

* it must be before the "{talendTypes}" key.

* 2. {talendTypes} 's value must be talend Type, it is required . its value should be one of: String, char | Character,

* Short

* 3. {Category} define a category for the Function. it is required. its value is user-defined .

* 4. {param} 's format is: {param} <type>[(<default value or closed list values>)] <name>[ : <comment>]

* <type> 's value should be one of: string, int, list, double, object, boolean, long, char, date. <name>'s value is the

* Function's parameter name. the {param} is optional. so if you the Function without the parameters. the {param} don't

* added. you can have many parameters for the Function.

* 5. {example} gives a example for the Function. it is optional.

public class PreviousDate {

/**

* helloExample: not return value, only print "hello" + message.

* {talendTypes} String

* {Category} User Defined

* {param} string("world") input: The string need to be printed.

* {example} helloExemple("world") # hello world !.

public static String GetSundayDate(String date) {

LocalDate date1 = LocalDate.parse(date) ;

LocalDate returnvalue = date1.minusDays(1);

String r=(returnvalue.toString());

return r;

}

There is a built-in function TalendDate.addDate(), you can find more information about this function in Repository-->Code--Routine>System-->TalendDate, try it!
