Request for nested loop example

[GoogleCodeExporter]

Hi I am new to lambdaj. I went through the examples of lambdaj and was able to 
get my initial requirement working. Now i want to use nested loops on 
collection to filter the lists based on some condition. Is this possible to do 
in lambdaj or should i follow the conventional method?

forEach(Person person:personList){

  forEach(Account account:person.getAccountList()){

          if(condition){
          }
    }
}

Second thing is can i perform inner join operation similar to SQL in lambdaj ? 
Is there any example ?

Kindly Reply

Thank You
Vijay
