      How to Enable Java

      The Java Virtual Machine (JVM) is a collection of software programs and data modules that forms part of the Java and Java 2 platforms. JVM works across all platforms and it alters Java bytecode into machine understandable code and executes it. It acts as a clone of a Java processor allowing Java bytecode to be

      JNI (Java Native Interface)

      The JNI (Java Native Interface) is a layer of Java that permits code executing or running in the JVM (Java Virtual Machine) to invoke and to be called by native libraries and applications written in other languages. The JNI is most commonly used with the C++, C, and Assembly programming languages. Typically, code developers will

    • Java Servlet

      Java Servlet

      A Java Servlet is the Java technology used to extend and improve Web server functionality. Servlets are able to provide a platform independent way to build web-based applications founded upon components without the performance limitations found with comparable CGI applications. Since Java Servlets are platform and server independent, they can be deployed across the full

    • Postfix


      The sum of X and Y is written as X+Y where + is the operator while X and Y are the operands. We have always learnt to write the sum of two numbers as X + Y; this notation is know as infix. Here, we’ll be talking about the postfix notation of representing arithmetic operations.

      Java Decompiler

      A Java decompiler is a special type of decompiler which takes a class file as input and produces Java source code as output. De-compilation is exactly the reverse process of compilation. However, decompilation will never produce an exact replica of the source code but does give back a major percentage. This is because quite a bit

    • Address Calculation Sort

      In this method, a function fn() is applied to each key. The result of this function determines into which of the several sub-files the record is to be placed. The function should have the property that x <= y, fn (x) <= fn (y). Such a function is called order preserving. Thus all of the

      How to Find Security Vulnerabilities in Source Code

      The original, and still the best, method for finding security vulnerabilities in source code is to read and understand the source code. Source code security vulnerabilities will vary between languages and platforms. Items to look for in C code include: Potential vulnerability Function calls to examine for vulnerabilities Buffer overflows gets(), scanf(), sprintf(), strcat(), strcpy()

      How to Sign a Java Applet

      Java applets are designed to run in a restricted environment known as Sandbox. This confinement helps avoid malicious activities and breach of security from intentionally harmful applets. Therefore, an applet cannot access or communicate with any outside-the-sandbox resource unless granted permission by the user. The trustworthiness of an applet is showcased by signing it with

Hexadecimal is used because it is easier for most humans than working in binary. In addition, hexadecimal is frequently useful because computers tend to work with 8-bit
