cURL (Client Uniform Resource Locator)

Image
  Introduction cURL was first released in 1997. It was originally named HTTP get and then became URL get before adopting the current name of cURL.

What is cURL? cURL stands for client URL and can be written as cURL which is used for file transfer with a URL syntax. It supports a number of protocols including HTTP, HTTPS, FTP, and many more. HTTP / HTTPS uses cURL to interact with APIs. cURL can be used on any machine and anywhere specially the basic cURL commands. Where to use cURL? cURL is used in a terminal or command prompt but the system should have it installed. Mostly used with Linux and it can be found in windows as well depending on the version that is being used. cURL also has 2 products: libcURL:  A free and easy to use client-side URL transfer library, supporting FTP, TPS, HTTPS, GOPHER, TELNET, DICT, FILE and LDAP, lib...

JDK Version Differneces

Image
  JDK Versions Java version language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library. Since J2SE 1.4, the evolution of the java language has been governed by the Java Community Process(JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform.        JDK vs JRE JRE(Java RuntimeEnvironment) is needed to run a Java program. A JRE includes, among other things, the Java Virtual Machine(JVM) and the "java" command-line tool. To develop new Java programs, you need to download a JDK(Java Development Kit). A JDK includes everything the JRE has, as well as the compiler javac and a couple of other tools like javadoc(Java documentation generator) and jdb(Java Debugger).     JDK versions    JDK 1 Basic Features   This was the initial release. This had very unstable APIs and one java web browser named WebRunner. First...

Object Oriented Programming

Image
  Object Oriented Programming Object Oriented Programming(OOP) is a programming concept that works on the principles of abstraction, encapsulation, inheritance, and polymorphism. It allows users to create the objects that they want and then, create methods to handle those objects. Basic concept of OOP is to create objects, re-use them throughout the program, and manipulate these objects to get results.   Class Class is a group of similar entities. It is only an logical component and not the physical entity.  Ex: if you have a class called "Racing Cars" it could have objects like Subaru, Nissan, Honda, BMW, etc. Its properties(data) can be price, max_speed, horse_power of these cars. While methods maybe performed with these cars are driving, reverse, braking etc. Object An object can be defined as an instance of a class, and there can be multiple instances of a class in a program. An Object contains both the data and the function,which operates on the data  Ex:chair,b...
