Question

Write a program that computes and prints the sum of integers from A to B. Create an appropriate class Summer that has a sum method that takes the range of numbers (A and B) from the user and returns the sum. Create a second class (SummerTester) with a main method to construct two objects of the Summer class and call the sum method to print out the result. For example: assume A = 1 and B = 100, the Sum will be: 1 + 2 + 3 + 4 + . . . + 100

Can you write the code which is easily understandle for NetBeans software and it uses javaDoc style. Thanks

Explanation / Answer

public class SummerTester{
public static void main(String[] args){

Summer s1=new Summer();

System.out.println("Sum of numbers between 1 and 100:"+s1.sum(1,100));
Summer s2=new Summer();
System.out.println("Sum of numbers between 1 and 10:"+s2.sum(1,10));

   }

}

package mani;

public class Summer {
public int sum=0;
   public int sum(int i, int j) {
      
       for(int x=i;x<=j;x++){
           sum=sum+x;
       }
       return sum;
   }

}
