Convert Long into Integer

Question

How to convert a Long value into an Integer value in Java?

Answer 1

In Java 8 you can use Math.toIntExact. If you want to handle null values, use:

Integer intVal = longVal == null ? null : Math.toIntExact(longVal);

Good thing about this method is that it throws an ArithmeticException if the argument (long) overflows an int.
