How do you initialize an array variable in java program?

Answer 1

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

Answer 2

int size=10;

int a[]=new Int[size];

this is static initialization;

int aa[]=null;

int size;

size you can take from your applicatin

aa[]=new int[size];

this is what dynamic initialization
