About Core Java Online Training
Java is an Object Oriented Programming Language which is developed by Sun Microsystem. It is platform independent language. Core Java is a concept to write once can be used anywhere. Without compiling the code it can be used on another platform if it the code is written for one platform. Java can be used in both Client Server as well as Web-based Application. We can use Core Java in many technologies like Selenium, Hadoop, Sales Force, Data Analytics, etc. It has the different concept of Collection, Swing, Multi threading, etc which help in the building of Stand-Alone Application. It is very flexible and can be used to develop Software as well as Applets. It is also used to develop Mobile Application, Desktop Application, Web Application, Security driven Application, etc. This Core Java Online Training is conducted by Real-Time Experts.
