Java Array

     We know that variables are used to store data in a Java program. We also know that each variable can store not more than one data item. So, what do we do if we need to store a large number of data items, say 50. Well, we can use 50 variables, one for each of the 50 data items, but we need to write 50 lines of code for setting up these variables, or we can use ARRAYs. Which will need just a single line. Most real-world programs handle vast amount of data. An array with loops can relatively handle a vast amount of data.
