Java Topic / Java tutorial Classes are supported by every object oriented programming language and they can be used to group related data.

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.
