This Java programming example will teach you the the concepts of arrays so that you can write a program on array by yourself. An array works a container object which can hold a values of same type. The length of an array is created when the array is going to be created. Arrays can be created in following ways. One way to create a array is by using new operator. e.g.. : a = new int;. It will create an array of type int which can store 5 integer values. The next way to define array is just same as we have defined an array in the program below. Array should be used, where you have to store multiple values of the same type. For example if we have to store months of the year then the better idea is to make an array of it.
In the program below we have defined a class named FirstArrayProgram. Now declare a method in which you have to define a array of String type which can hold only string values. In this array we are storing a months of the year. Now we want to retrieve the values of an array, so use for loop to access it.
Code of the program is given below
The output of this program is given below:
Name of months in a year :
Rs. 20,000 US$ 300
Today: Rs. 10,000 US$150
Course Duration: 30 hrs
