Here is some very exciting Java code for printing 5.



import java.security.*;

import java.lang.reflect.*;

import java.util.*;



public class Test

{

    public static void main(String[] args) throws Exception

    {   

        AccessController.doPrivileged( new PrivilegedAction(){ public Object run(){try {

        Field field = Class.forName("java.lang.Integer$IntegerCache").getDeclaredFields()[0];

        field.setAccessible(true);



        Integer[] cache = (Integer[])field.get(null);

            

        cache[130] = 3;  

            

        Integer foo = 2;

 

        System.out.println(foo + 2); 

            

        return null;} catch(Exception e) { throw new RuntimeException(e); } } }); 

    }





}
