Turning multi-line string into array in java

I am making a function that can turn a number into a simplified radical square root. I have so far made a function that can return the factors of a number. I want to turn the string into an array so I can index through the numbers in a for loop and test if they have a perfect square root. How can I do this?

This is what I have so far:

  public static void factor(int num) {      for (int i = 1; i <= num; ++i) {        if (num % i == 0) {          System.out.println(i);        }      }    }  

inputing the number 20 outputs

1  2  4  5  10  20  

I want to turn this into {1, 2, 4, 5, 10, 20}
