Write a program to display the possible sum Consecutive numbers to developed a given number.

Accept a number from the user and put into a loop to find the Consecutive Numbers and store the numbers in a string. Now print the string a result.

import java.util.*;
class Consecutive
{
    public static void main()
    {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the number:");
        int num = sc.nextInt();
        int sum;
        String str;
        for(int i=1;i<num;i++)
        {
            sum=0;
            str="";
            for(int k=i;k<num;k++)
            {
                sum += k;
                if(str.equals(""))
                {
                    str += k;
                }
                else
                {
                    str += "+" + k;
                }
                if (sum==num)
                {
                    System.out.println(str);
                }
                else if(sum>num)
                {
                    break;
                }
            }
        }
    }
}

Enter the number:
15
1+2+3+4+5
4+5+6
7+8
