JOptionPane Looping

I have an issue. My lecturer wants me to make a loop, with an input of JOptionPane and an output of console. How can I use loop for JOptionPane and send an output through console.

Here's my code:

int even=0;
int odd=0;
int e_e=0;
int o_o=0;

String a1 = JOptionPane.showInputDialog(null,"Type in 10 integer");

for (int counter=0; counter<10;counter++){
  int a = Integer.parseInt(a1);

    if (a%2==0){
        even++;
        e_e += a;
    } else {
        odd++;
        o_o +=a;
    }
}

System.out.println("\n\nNumber of even numbers : " + even);
System.out.println("Number of odd numbers : " + odd);
System.out.println("Total of even numbers : " + e_e);
System.out.println("Total of odd numbers : " + o_o);
