int number = 110101; 
String temp = Integer.toString(number);
int[] numbers = new int[temp.length()];
for (int i = 0; i < temp.length(); i++) {
    numbers[i] = temp.charAt(i) - '0';

Example 3: java array declaration

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

int[] theNumbers = new int[5];

arr[0] = 4;
arr[1] = 8;
arr[2] = 15;
arr[3] = 16;
arr[4] = 23;
arr[5] = 42;

Example 5: java how to initialize an array

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

Example 6: how to initialize array in java

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