(x^2)/4 code example

Example 1: 2+2=5

import java.lang.reflect.Field;

public class Main {
    public static void main(String[] args) throws Exception {
        Class cache = Integer.class.getDeclaredClasses()[0];
        Field c = cache.getDeclaredField("cache");
        c.setAccessible(true);
        Integer[] array = (Integer[]) c.get(cache);
        array[132] = array[133];
        System.out.printf("%d",2 + 2);
    }
}

Example 2: 64 x 2.5 x 3 x 7

64 x 2.5 x 3 x 7 = 3360
