Question

Write a java program named SumThousand The program adds all the number from 1 to 1000 together and print out the sum

Answer 1

Answer:

The program in Java is as follows:

public class SumThousand  {

   public static void main(String args[]) {

     int sum=0;

     for(int i =1;i<=1000;i++)

         sum+=i;

     

     System.out.println("Sum = " + sum);

   }

}

Explanation:

This initializes sum to 0

int sum=0;

This iterates from 1 to 1000

     for(int i =1;i<=1000;i++)

This calculates the required sum

         sum+=i;

     

This prints the calculated sum

     System.out.println("Sum = " + sum);
