Hi everyone,

I am very new to this platform and do not have much knowledge.

I want to study Web Services.

Kindly guide me with necessary documents.

I have already gone through the Apex developer guide.

Thanks.

Hi,

Please look at the below 2 code snippets:

 1)  

public class selectedRecords {
public List<clsWrapper> accls=new List<clsWrapper>();

2)

public class selectedRecords {
public List<clsWrapper> accls{get;set;}
public List<clsWrapper> getAccounts(){
accls=new List<clsWrapper>();
if(accls==null && accls.size()==0){
for(Account a: [select id, Name from Account limit 10]){
accls.add(new clsWrapper(a));
}
}
return accls;
}

}

 mY question is: what is the differnence between allocating memory to the list in starting of class and inside getter ?
