casting - Cast Double to Integer in Java

Question

Any way to cast java.lang.Double to java.lang.Integer?

It throws an exception

"java.lang.ClassCastException: java.lang.Double incompatible with java.lang.Integer"

Answer 1

You need to explicitly get the int value using method intValue() like this:

Double d = 5.25;
Integer i = d.intValue(); // i becomes 5

Or

double d = 5.25;
int i = (int) d;
