如何从用户读取多个输入以在Java中进行数组操作

Question

How do i take multiple inputs from user and print the result as per the input. For example in the below codec i want to take multiple 11 digit number from user and print the result Y or N for each input by user as per the given if else condition.

public class Test {

public static void main(String args[]){

    Scanner sc = new Scanner(System.in);
    System.out.println("Enter 11 digit  number");
    String s = sc.nextLine();
    int[] a=new int[12];
    for(int i=0;i<s.length();i++){
        a[i] = Character.getNumericValue(s.charAt(i));  
    }

    int result = a[0] + a[1] *3+ a[2] * 7 + a[3]*9 + a[4] + a[5] * 3 + a[6] * 7 + a[7] * 9 + a[8] + a[9] * 3 + a[10];
    if(result%10==0){
        System.out.println("Y");
        }
    else{
        System.out.println("N");
        }

   }
}

Any help would be appreciated.

Answer 1

Please do something like below :

 Scanner scanner=new Scanner(System.in);
    while (true) {
        System.out.println("Enter 11 digit number and press Q to quit");
        String number= scanner.nextLine();
        if(question.equals("Q")){
            break;
        }
      }

In condition you can put condition when to terminate the loop as mentioned in below ans.

 public static void main(String[] args) {

       Scanner sc = new Scanner(System.in); 

       while(sc.hasNextLine()){

       System.out.println(sc.nextLine());

      }
     }
