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

Question

I\'m getting the following exception.

Caused by:

java.lang.ClassCastException: java.math.BigInteger cannot be cast to java.lang.Integer

Answer 1

java.lang.Integer is not a super class of BigInteger. Both BigInteger and Integer do inherit from java.lang.Number, so you could cast to a java.lang.Number.

See the java docs http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Number.html
