Convert Long into Integer

Question

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

Answer 1

The best simple way of doing so is:

public static int safeLongToInt( long longNumber ) 
    {
        if ( longNumber < Integer.MIN_VALUE || longNumber > Integer.MAX_VALUE ) 
        {
            throw new IllegalArgumentException( longNumber + " cannot be cast to int without changing its value." );
        }
        return (int) longNumber;
    }
