Check out example codes for "java array initialization". It will help you in understanding the concepts better.

Code Example 1

int[] data = {10,20,30,40,50,60,71,80,90,91};
// or
int[] data;
data = new int[] {10,20,30,40,50,60,71,80,90,91};
// or
int[] data = new int[10];
data = {10,20,30,40,50,60,71,80,90,91};

Code Example 2

int[] data = {10,20,30,40,50,60,71,80,90,91};

// or

int[] data;
data = new int[] {10,20,30,40,50,60,71,80,90,91};

Code Example 3

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

Code Example 4

String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
cars[0] = "Opel";
System.out.println(cars[0]);
// Now outputs Opel instead of Volvo

Code Example 5

int[] arr = new int[5];	 // integer array of size 5 you can also change data type
