java - What design pattern would fit my needs? -

i have next class:

public class { private string a; private long b; private date c; //getters, setters, constructors }

and need able export excel different templates. example, 1 excel has next headers: b c

another excel has next template: b c

and template this: b a

what way design code format object according 1 template or another? there particular design pattern can at?

i think can utilize adapter pattern, need create different adapter different templates.

bind object adapter , logic in adapter assign value passed object template want fill values.

by making adapter can create new format without making alter in existing format, create code more maintainable , separate.

this rough thought concept can apply here, still have scope of making many modification in it.

adapter interface

public interface adapter { }

adapter class

public class format2adapter implements adapter { private long title; string subtitle; public void filltemplate(core c){ title = c.getb(); } }

format2adapter class

public class format2adapter implements adapter { private long title; string subtitle; public void filltemplate(core c){ title = c.getb(); } }

business object class

import java.util.date; public class core { private string a; private long b; private date c; public string geta() { homecoming a; } public void seta(string a) { this.a = a; } public long getb() { homecoming b; } public void setb(long b) { this.b = b; } public date getc() { homecoming c; } public void setc(date c) { this.c = c; } // getters, setters, constructors }
