How do you write a function that outputs?

How do you write a function that outputs the largest and the smallest number amongst three integer inputs? Also, let the user choose whether to end the program or not (do while)?

Program

import java.util.Scanner;
public class Main
{
 public static void main(String[] args) {
  findLargestAndSmallest();
 }
	
 public static void findLargestAndSmallest(){
     int num=0, max=0, min=0, i=1;
        char choose='n';
    Scanner sc = new Scanner(System.in);
    do{
        System.out.printf('Enter %d number : ',i++);
        num = sc.nextInt();
        if((i-1) == 1){
            max = min = num;
            continue;
        }
        if(num>max)
        { 
            max = num;
        }else if(num<max && num<min)
            min = num;
        if(i>3){
            System.out.printf('\nYou want to close the program,\nIf Yes then press : Y\nIf No then press : N\n');
            choose = sc.next().charAt(0);
        }
        if(choose == 'Y' || choose =='y'){
            System.out.printf('Max value is :%d and Min value is : %d',max,min);
            break;
        }else{
            continue;
        }
    }while(true);
 }
}

Output.

Enter 1 number : 34

Enter 2 number : 23

Enter 3 number : 12

You want to close the program,

If Yes then press : Y

If No then press : N

n

Enter 4 number : 0

You want to close the program,

If Yes then press : Y

If No then press : N

y

Max value is :34 and Min value is : 0
