How to define a custom type for both account and contact object using Wrapper class in Salesforce?

Hello Chanchal,

You can refer to the following example to  define a custom type for both acccount and contact object using wrapper class:

public with sharing class conacc {

public List<MyWrapper> wrapper {get; set;}

public List<Account> accLst1 {get; set;
public List<Contact> conLst1 {get; set;}

public conacc ()

{
accLst1 = [select id,Name from Account ] ;
conLst1 = [select Id,Name from contact where AccountId IN : accLst1 ] ;
wrapper = new List<MyWrapper>() ;
for(Integer i=0 ; i < 20; i++)
wrapper.add(new MyWrapper( conLst1, accLst1[i])) ;
System.debug('----------'+ wrapper);
}
public class MyWrapper
{
public Account accRec1 {get; set;}
public List<Contact> conRec1 {get; set;}
public MyWrapper( List<Contact> con ,Account acc )
{
accRec1 = acc ;
conRec1 = con ;
}

}

}
