Question

Must use Array. Must be in JAVA.

Write a program that uses a Scanner object to read in a sequence of integers. The first number in the sequence represents the number of integers in the sequence (i.e., do NOT include the first number as part of the sequence).

Create an array of integers that is the same size as the number of integers. Then the program will read each integer and place it in the array. Print the content of the arrays on one line (each integer separated by a comma).

Details

Input

A sequence of integers, where the first integer represents the number of integers.

Example Input: 5 31 5 18 9 10

Output

Print the array contents with a comma separating the numbers on one line.

Example Output: 31, 5, 18, 9, 10

Answer 1

CODE:

import java.util.*;
public class ReadElement
{
    public static void main(String args[])
    {
        Scanner sc = new Scanner(System.in);
        String line = sc.nextLine();
        line+=" ";
        String w="";
        int i=0;
        while(line.charAt(i)!=' ')
        {
            w += line.charAt(i);
            i++;
        }
        int size = Integer.parseInt(w);
        int ar[] = new int[size];
        for(int k=0;k<size;k++)
        {
            i+=1;w="";
            while(line.charAt(i)!=' ')
            {
                w+=line.charAt(i);
                i++;
            }
            ar[k] = Integer.parseInt(w);
        }
        for(int k=0;k<size-1;k++)
            System.out.print(ar[k]+",");
        System.out.print(ar[size-1]);
    }
}

OUTPUT:
