Free ASCII Quick Reference Sheet

Scovetta — Fri, 29 Aug 2008 15:57:13 +0000

I tried finding a nice quick-reference ASCII table but didn’t find anything I liked, so I created my own. It is a single page PDF with all ASCII characters (regular and extended). Simple, easy, and printable.

Accessing Private Methods in Java

Scovetta — Mon, 18 Feb 2008 05:16:56 +0000

In every introductory Java programming class (and probably every tutorial or book), students are taught that private fields and methods can only be accessed by methods of the same class. Though this would seem to be a security control, using private visibility can be easily overridden, as shown below:


import java.lang.reflect.*;
class A {
  private void f() {
    System.out.println("Running A.f()");
  }
}

public class Main {
  public static void main(String[] args) throws Exception {
    Class a = new A().getClass();
    Method m = a.getDeclaredMethod("f", null);
    m.setAccessible(true);
    m.invoke(new A(), null);
  }
}
