Question of Java

Question

anybody know?How to transform a number (for example: n = 12345) to the massive of numbers {1,2,3,4,5}.

Answer 1

You could also take the last digit with: myNum % 10, then divide the number by 10, until it's zero. Adding the last digit to the end of the array each time.

Probably better than converting to String.

Answer 2

Here's a way you can do it without converting the number into a string:

public class Program
{
public static void main(String[] args) {
int number = 123456789;
int[] arr = new int[getNumberOfDigits(number)];

for(int i = arr.length - 1; i >= 0; --i) {
arr[i] = number % 10;
number /= 10;
}

for(int num: arr) {
System.out.println(num);
}
}

static int getNumberOfDigits(int number) {
int length = 1;

while((number /= 10) != 0){
++length;
}

return length;
}
}
