Answer 1

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.println("Enter the number");
    String str= input.nextLine();

    int ascii;
    for(int i=0; i= 65 && ascii <= 90) {
            System.out.println("captal letter found ::: "+ascii);
        }
    }
}
