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 …
The conversion from basic to user defined data types can be done using constructors. Consider the following constructor: .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; } .cl { margin: 0px; } .cb1 { color: green; } .cb2 { color: blue; } .cb3 { color: maroon; } String :: String(char *a) …
An integer overflow, or integer wrapping, is a potential problem in a program based upon the fact that the value that can be held in a numeric datatype is limited by the data type’s size in bytes. ANSI C uses the following minimum sizes: data type size (bytes) char 1 short 2 int 2 long …
“cannot resolve symbol” means that the Java compiler cannot locate a symbol referenced in your Java source code. The causes for this common error include: A missing class file A faulty CLASSPATH A symbol name is mispelled or miscapitalized A data type is incorrect, misspelled, or miscapitalized A method is called with the wrong number …
A hex editor is a program edits compiled programs and binary data files. These editors are called hex editors because they most often present data in hexadecimal format. 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 …

This FAQ answer is an excerpt from SNIPPETS by Bob Stout. Don't hold your breath. Think about it… For a decompiler to work properly, either 1) every compiler would have to generate substantially identical code, even with full optimization turned on, or 2) it would have to recognize the individual output of every compiler's code …
To understand what a format string vulnerability is, you first need to know what a format string is. A format string is a way of telling the C compiler how it should format numbers when it prints them. Format Strings in C In the C programming language there are a number of functions which accept …
A constructor plays a vital role in initializing an object. An important note, while using constructors during inheritance, is that, as long as a base class constructor does not take any arguments, the derived class need not have a constructor function. However, if a base class contains a constructor with one or more arguments, then …
The javascript:void(0) error is fairly unique, in that it is one of the few computer-based errors that can be encountered by users of any operating system.
