how to cast long value to int

This is just memo about how to cast long value to int.
From JavaSE8 you can use Math.toIntExact to avoid overflows while you do not know.

Sample.java

public class Sample {
    public static void main(String... args) {
        Sample sample = new Sample();
        sample.cast();
        sample.intExact();
    }
    void cast() {
        System.out.println("----- cast -----");
        int i;
        long l = Long.MAX_VALUE;
        i = (int) l;
        System.out.println(String.format("i=%d", i));
        System.out.println(String.format("l=%d", l));
    }
    void intExact() {
        System.out.println("----- intExact -----");
        int i;
        long l = Long.MAX_VALUE;
        i = Math.toIntExact(l);   // <--- This method was added from JavaSE8
        System.out.println(String.format("i=%d", i));
        System.out.println(String.format("l=%d", l));
    }
}

The result

The following result shows the difference between cast and Math.toIntExact.
