import java.io.; import java.util.;

public class Solution {

public static void main(String[] args) {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
    Scanner sc= new Scanner(System.in);
    List <Integer> first=new <Integer>ArrayList();
    int n=sc.nextInt();
    for(int i=0;i<n;i++){
        int m=sc.nextInt();
        first.add(m);
    }
    int q=sc.nextInt();
    for(int i=0;i<q;i++){
        String value=sc.nextLine();

        if(value.equals("Insert")){
        int x=sc.nextInt();
        int y=sc.nextInt();
            first.add(x,y);
        }

          else{
            int k=sc.nextInt();
            first.remove(k);
        }
    }
    for(Integer z:first)
        System.out.print(z+" ");
}

} ques------why I am getting input mismatch exception?

Exception in thread "main" java.util.InputMismatchException at java.util.Scanner.throwFor(Scanner.java:864) at java.util.Scanner.next(Scanner.java:1485) at java.util.Scanner.nextInt(Scanner.java:2117) at java.util.Scanner.nextInt(Scanner.java:2076) at Solution.main(Solution.java:26)
