You can use scanner.nextInt() method , it will take care of new line and space character. Please find below code snippet.

Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
int x = sc.nextInt();
int y = sc.nextInt();
for (int i=0;i<x;i++) {
    int temp = sc.nextInt();
    System.out.println(temp);
