Answer 2

Arrays are nothing but objects. In Java you have 8 primitive data types and the rest are reference types.

Arrays can hold any of these types. In order to declare an Array, you just have to write the below line-

Type[ ] array_name = new Type[size];
// this is called array declaration.

You can replace the Type with anything, it could be either primitive types, wrapper classes or even user defined types.

A simple example would be-

int[ ] abc = new int[ 5 ];

Here you have created an integer type array which can store 5 values of integer type only.
To store values you can do-
abc[0] = 10;
abc[1] = 20;
abc[2] = 30;
etc...
Always remember array indexing starts from 0 so the above array can hold indexes from 0 to 4 which are totally 5 in number.
