Check out example codes for "how to create an array in java". It will help you in understanding the concepts better.

Code Example 1

int[] array = new int[/*size*/];
// Works for double, char, etc.

Code Example 2

//Metodo 1
type nome = new type[n];

//Metodo 2
type nome[];
nome = new type[n];

Code Example 3

int[] intArray = new int[]{ 1,2,3,4,5,6,7,8,9,10 }

Code Example 4

int[] arr = new int[10];	//Can hold 10 elements

Code Example 5

int[] array1 = new int[5]; //int array length 5
String[] array2 = new String[5] //String array length 5
double[] array3 = new double[5] // Double array length 5

Code Example 6

An array is an ordered collection of elements of the same type, identified by a pair of square brackets []. 
 
 To use an array, you need to:
1. Declare the array with a name and a type. Use a plural name for array, e.g., marks, rows, numbers. All elements of the array belong to the same type.
2. Allocate the array using new operator, or through initialization, e.g.
  
  int[] marks;  // Declare an int array named marks
              // marks contains a special value called null.
int marks[];  // Same as above, but the above syntax recommended
marks = new int[5];   // Allocate 5 elements via the "new" operator
// Declare and allocate a 20-element array in one statement via "new" operator
int[] factors = new int[20];
// Declare, allocate a 6-element array thru initialization
int[] numbers = {11, 22, 33, 44, 55, 66}; // size of array deduced from the number of items
