An array in java is a collection of items stored into a single unit. The array has some number of slots (elements), each slot in the array can hold an object or a primitive value. Arrays in java are objects that can be treated just like other objects in the language
Arrays can contain any type of element value , but we can't store different types in a single array. We can have an array of integers or an array of strings or an array of arrays.
To create an array in java ,use three steps
1. Declare a variable to hold the array
2. Create a new array object and assign it to the array variable
3. Store things in that array
