Very clear. "java.lang.ClassCastException: java.lang.Double incompatible with java.lang.Integer"You need to explicitly get the int value using method intValue() like this:I think it's impossible to understand the other answers without covering the Actually there is a shortcut. We can convert int to double in java using assignment operator. To convert double data type into int, we need to perform typecasting.

If you want the Integer nearest to the Double value, you'll need to do this:. But I think this code is clearer for people who haven't quite grasped objects and primitives yet.Whomever down-voted this answer: You'll help the community a lot more if you explain why, and it might even help you find out why it didn't work for you.
