      How to Debug Java

      The ability to debug any modern programming language is a critical skill for programmers of all skill levels. Learning how to debug Java helps developers discover the causes of logic and non-trivial syntax errors that prevent proper execution of Java programs. The ability to step-through a Java program using a debugging environment provided by updated

      Java

      Java was originally developed as an implementation of a programming language that would compile and complete its directive functions regardless of platform and language version. It was developed by James Gosling, a software developer employed by Sun Microsystems in June of 1991, whom released the first version of Java in 1995. The language is designed

    • File Input/Output

      File Input/Output

      In C++, file input/output services are implemented through a component header file available in the C++ standard library. This header file is fstream.h . In C++, a file, at its lowest level, is interpreted simply as a sequence, or stream, of bytes. One aspect of the file I/O library manages the transfer of these bytes.

    • Disassembler

      Disassembler

      A disassembler is a software that is able to convert an executable language into an assembly language, allowing users to view the individual commands that make a program work. A disassembler is ideal for programming applications because it can be useful when a programmer is attempting to create a similar program to one he/she already

    • break and continue Statements

      break and continue Statements

      break Statement The break statement is used to alter the flow of control. When a break statement is executed in a while loop, for loop, do-while loop or switch statement, it causes immediate exit from that statement. Program execution continues with the next statement. Common uses of the break statement are to escape early from

      Trees

      Arrays, linked lists, stacks and queues are used to represent linear and tabular data. These structures are not suitable for representing hierarchical data. In hierarchical data we have ancestors, descendants superiors, subordinates, etc Family Structure Business Corporate Structure Federal Government Structure Introduction to Trees Fundamental data storage structures used in programming Combine advantages of ordered

    • Random Number Vulnerability

      Random Number Vulnerability

      Computers are deterministic and are therefore predictable. Computers cannot, in and of themselves, generate truly random numbers. In the absence of outside input, computers can only create pseudo-random numbers.¬† In the words of John Von Neumann, “Anyone attempting to produce random numbers by purely arithmetic means is, of course, in a state of sin.” A

    • Java Decompiler

      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

    • Integer Overflow

      Integer Overflow

      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
