How to Iterate through List of Object arrays

Question

So right now I have a program containing a piece of code that looks like this...

Criteria crit = session.createCriteria(Product.class);
ProjectionList projLi         


        

Answer 1

You can probably do something like this:

for (Object result : results) {
    // process each result
}

Answer 2

In this case you will have a list whose elements is an array of the following: [maxPrice,minPrice,count].

....
List<Object[]> results = crit.list();

for (Object[] result : results) {
    Integer maxPrice = (Integer)result[0];
    Integer minPrice = (Integer)result[1];
    Long count = (Long)result[2];
}

Answer 3

You could use Generic in List and for each but for current code you could do following to iterate

for(int i = 0 ; i < results.size() ; i++){
 Foo foo = (Foo) results.get(i);

}

Or better to go for readable for-each loop

for(Foo foo: listOfFoos){
  // access foo here
}
