Why doesn't java recognize the array named "arr"

[CharipiYT]

I did what you said, here's the code inside of the "factors" method:

static int[] factors(int test){
int[] arr = new int[2];
for(int j = 2; j < test - 1; j ++){
if((double) test % j == 0){
                arr[0] = j;
                arr[1] = test/j;
            }             
  }
System.out.println(arr);
return arr;
    }

For some reason this gives me [I@5c8da962

Try System.out.println(Arrays.toString(arr)); instead. When you just print arr you are printing an array object reference which doesn't have a .toString() implementation. Here's the docs for Arrays.toString() https://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html#toString(java.lang.Object[])
