Answer 1

//TestCode.java
import java.util.Scanner;
public class TestCode {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.print("Input a sequence of die toss values: ");
        String s = scanner.nextLine();
        String[] splits = s.split(" ");

        int counts[] = new int[6];
        int n;

        for(int i = 0;i<counts.length;i++){
            counts[i] = 0;
        }

        for(int i = 0;i<splits.length;i++){
            n = Integer.parseInt(splits[i]);
            counts[n-1]++;
        }

        System.out.println("Toss value\t\tCount");
        System.out.println("----------------------");
        for(int i = 0;i<counts.length;i++){
            System.out.println((i+1)+"\t\t\t\t"+counts[i]);
        }
    }
}
