Question

I have an array where I have some numbers. Now I want to sort even numbers in a separate array and odd numbers in a separate. Is there any API to do that? I tried like this

int[] array_sort={5,12,3,21,8,7,19,102,201};
int [] even_sort;
int i;
for(i=0;i<8;i++)
{

if(array_sort[i]%2==0)
{
     even_sort=Arrays.sort(array_sort[i]);//error in sort
        
System.out.println(even_sort);
}
}

Answer 1

Plain and simple.

int[] array_sort = {5, 12, 3, 21, 8, 7, 19, 102, 201 };

List<Integer> odd = new ArrayList<Integer>();
List<Integer> even = new ArrayList<Integer>();
for (int i : array_sort) {
    if ((i & 1) == 1) {
        odd.add(i);
    } else {
        even.add(i);
    }
}
Collections.sort(odd);
Collections.sort(even);
System.out.println("Odd:" + odd);
System.out.println("Even:" + even);
