Java Array

Array, what is it? An array is a group of variables of the same data type and referred to by a common name. An array is contiguous block of memory locations referred by a common name.

Why array is needed?

You might come across a situation where you need to store similar type of values for a large number of data items. For example : to store all student mark , you need declare thousands of variables
 In addition, each variable name needs to be unique. To avoid such situations, you can use arrays do store the thousands of student mark.

For example Java Array
To store the marks of 5000 students, you can declare an array, marks, of size 5000 and can store the marks of as many students.

int marks[] = new int[5000];
