Now that we have understood how to convert basic data types to class types and vice-versa, it is time to learn how to convert objects of one class type to another class type. The conversion between objects of different classes can be done using either a one-argument constructor or a conversion function. The choice depends …
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 …
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 …
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 …
The programming language called PHP is quickly rising to be one of the most preferred web browser programming languages due to its user-friendliness, efficiency, and user control. PHP allows a user to describe specific functions within the code in order to drastically control the way a web browser displays and organizes information. A user is …
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() …
Java supports three types of loops: For, While, and Do. The Java For Loop The Java for loop is a looping construct which continually executes a block of statements over range of values. Java for Loop Syntax The syntax of a for loop in Java is: for (initialization; termination; increment) { statement } Example 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 …
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 …
Traversing a list A linear list can be traversed in two ways In order traversal Reverse order traversal In order Traversal To traverse the linear linked list, we walk the list using the pointers, and process each element until we reach the last element. .cf { font-family: Lucida Console; font-size: 9pt; color: black; background: white; …
