Java Topic / Java tutorial Classes are supported by every object oriented programming language and they can be used to group related data. For _EG_ if we take student details, although we can store the information about the student using primitive data types like int, double and char, it will be useful to have a separate type for student.

Java Topic / Java tutorial An important element of object oriented programming is abstraction. Abstraction is basically managing the complex activities with out knowing the details. For _EG_ when we call some one using the mobile, there are lot of operations which happen in the background, before the call reaches the other person. We need not know any of that information, but still be able to make a call.

Learning a computer language is very easy compared to writing good programs and using the language effectively. For a beginner, it might take 4-5 months to learn a new language where as perfecting the programming skills including the design, debugging and maintenance might take more than 3 to 4 years. Listed below are few of skills which everyone needs for becoming a good programmer.

Java Topic / Java tutorial Java in order to support 73:security and 73:portability, does not compile the source code to executable code. It is translated into bytecode, which is highly optimized set of instructions designed to be executed by the Java run-time system, which is called Java Virtual Machine (JVM). JVM is an interpreter of bytecode.

Java Topic / Java tutorial We have seen the class hierarchies - Entertainments example in 101 and IceCreamPrices example in 111. The class hierarchies look similar except that there is minor difference between them. IceCream is a concrete super-class where as Entertainment is an abstract super-class. The difference is explained below.

Java Topic / Java tutorial As discussed in 161 programming helps automating lot of time consuming activities and reduces the human errors. Every computer program needs to be written in one of the multiple computer languages which are available. One such programming language is Java.

Most of the activities we perform on day-to-day basis have lots of little steps. For e.g., an activity like send greeting card will contain small steps like go to the greeting card shop, choose it, pay for it, write the names and address, go to the post office, buy stamps, affix the stamps and drop the card in the post drop box. In this some steps like going to the post office, buying stamps and dropping the card in the post box are time-consuming and repetitive. Where as calculating the price of all the cards we bought, paying the money to the shop-keeper and counting the change returned is error prone. These kind of steps which does not need lot of human intervention and are not person dependent can be automated using Computer Programs. Please note that no matter how many steps we automate, there will be things like choosing the right card which needs the human intervention and the personal touch. The computer programs help in automating the tasks which are time consuming, error prone, repetitive, not person dependent etc., They also help in stream lining the processes, provide better experience to the end users, keeping track of historical data, analyze the data etc., Some programs are very expensive and could take 5 or more years with multiple teams working on it, while some might be relatively easy and can be built in matter of weeks by an individual developer.

Learn Java even if you dont know C/C++. Practice with 600 Java Programs and 2000 MCQs to perfect your learning. Compete and win prizes/certificates.

Java Topic / Java tutorial Java was conceived by James Gosling, Patrick Naughton, Chris Warth, Ed Frank and Mike Sheridan at Sun Microsystems, Inc in 1991. Initially it was called Oak, later it was changed to Java in 1995.

Now we can discuss any technical questions, suggestions, feedback or improvements here. Hope this will make learning easier.
