  6. Write a Java program to find sum of all natural numbers between 1 to n. Static :-  class loop6 { public static void main(String args[]) { int i=1,j=10,sum=0; while(i<=j) { sum = sum +i; i++; System.out.println(sum); } } } Output :-  Dynamic :-  import java.util.*; class loop6 { public static void main(String args[]) { Scanner in = new Scanner(System.in); int i,j,sum=0; System.out.println("Enter the Stating number :-"); i=in.nextInt(); System.out.println("Enter the Ending number :-"); j=in.nextInt(); while(i<=j) { sum = sum + i; i++; } System.out.println(sum); } } Output :-
