Doing a yes or no where yes continues but terminates after asking

Question

After putting all the numbers input the loop terminates and the program ends, after asking whether to continue or not.

import java.util.Scanner;

public class coding {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner in = new Scanner (System.in);
        String choose;
        int i;
        double ans;

        do {
            int num1= in.nextInt();
            int num2= in.nextInt();
            int num3= in.nextInt();
            int num4 = in.nextInt();
            int num5 = in.nextInt();
             ans = (num1+num2+num3+num4+num5)/5;
            System.out.println(ans);
            //in.nextLine();
            System.out.println("Continue the program Yes or N?");
            
            choose = in.nextLine();


        }while (choose.equalsIgnoreCase("Yes"));

    }

the program will continue on Yes and will end on N, so you need to change it the while condition to this: !choose.equalsIgnoreCase("N") to check while its not true then iterate.

secondly you used choose = in.nextLine(); which cause error on next iteration, which you need to change it to choose = in.next(); to run without error.

choose = in.nextLine(); it cause to store the enter value in next call of in.nextInt() and throw an error.

Scanner in = new Scanner(System.in);
String choose;
int i;
double ans;

do {
    int num1 = in.nextInt();
    int num2 = in.nextInt();
    int num3 = in.nextInt();
    int num4 = in.nextInt();
    int num5 = in.nextInt();
    ans = (num1 + num2 + num3 + num4 + num5) / 5;
    System.out.println(ans);
    // in.nextLine();
    System.out.println("Continue the program Yes or N?");
    choose = in.next();

} while (!choose.equalsIgnoreCase("N"));
