java.math.BigInteger cannot be cast to java.lang.Long

Question

I\'ve got List dynamics. And I want to get max result using Collections. This is my code:

List dynamics=spy         


        

Answer 1

Your error might be in this line:

List<Long> result = query.list();

where query.list() is returning a BigInteger List instead of Long list. Try to change it to.

List<BigInteger> result = query.list();

Answer 2

Try to convert the BigInteger to a long like this

Long longNumber= bigIntegerNumber.longValue();
