Narrowing Casting

Example

public class Main {
    public static void main(String[] args) {
        double price = 99.99;
        int rupees = (int) price;       // decimal part is cut off, not rounded
        System.out.println(rupees);

        long big = 3_000_000_000L;
        int small = (int) big;          // too big for int -> wraps around
        System.out.println(small);

        int code = 66;
        char ch = (char) code;
        System.out.println(ch);

        System.out.println((int) 7.9 + " " + (int) -7.9);
        System.out.println(Math.round(7.9));   // round instead of truncate
    }
}
