Introduction

After going through the primitive data types of java, many of us will have a question can we store more than one entry sequentially in the disk?. Arrays in java would be the answer to our query.

An array is a data structure that stores the entries of the same data type sequentially. An array reduces the duplication of code and makes it simple. When we want to store a considerably big number of values, say 50 values then assigning each value to a variable contradicts the simplicity of a code.

An array overcomes this issue we can assign all these values to a single array but remember that an array can store only values of the same data type.
