      Java Data Types

      Data types in the Java programming language are basically divided into two groups – primitive data types and object references. A primitive data type is a basic building block and has full built-in support. Many other languages also support composite data types, which are build on a combination of primitive data types and may or

    • Java Package

      Java Package

      A Java package is a set of classes which are grouped together. This grouping helps to organize Java classes and codevent multiple Java classes with the same name. Using Java Packages To use a package in your Java source code, you must either import the package or use the fully qualified class name each time

    • JNI (Java Native Interface)

      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

      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 Loops – For, While, and Do

      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

      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

    • 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

      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

      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
