I would like to convert an integer into an array, so that it looks like the following:
int number = 123456 ;
int array[7] ;
with the result:
array[0] = 1
array[1] = 2
...
array[6] = 6
771
Using the toArray() method − The toArray() method of the Set interface accepts an array, populates it with all the elements in the current set object and, returns it. using this method, you can convert a Set object to an array.
To convert all elements in an array to integer in JavaScript, w ecan use the array map method. const arrayOfNumbers = arrayOfStrings. map(Number);
An array can be converted to an ArrayList using the following methods: Using ArrayList. add() method to manually add the array elements in the ArrayList: This method involves creating a new ArrayList and adding all of the elements of the given array to the newly created ArrayList using add() method.
Perhaps a better solution is to work backwards:
123456 % 10 = 6
123456 / 10 = 12345
12345 % 10 = 5
12345 / 10 = 1234
190
just use modular arithmetic:
int array[6];
int number = 123456;
for (int i = 5; i >= 0; i--) {
array[i] = number % 10;
number /= 10;
}
