I am in java intro class the for loop problem involvies comp

I am in java intro class, the for loop problem involvies computing the value of pi. I need to compute the first 400,000 terms of this series. Print every 100th value to the screen using the equation given below. I am particularly struggling with how to begin the for loop and what to write in it.

pi = 4 - (4/3) + (4/5) - (4/7) + (4/9) - (4/11)....etc

Solution

Hi friend please find my code.

Please let me know in case of any issue.

public class PiSeries {

   public static void main(String[] args) {

       double piValue = 0;

       int count = 0;

       int lowerTerm = 1;

       for(int i=1; i<=400000; i++){ // iterating from 1 to 400000

           if(i%2 == 1) // if i is odd, then we need to add

               piValue = piValue + 4.0/lowerTerm;

           else

               piValue = piValue - 4.0/lowerTerm;

           lowerTerm = lowerTerm + 2;

           count++;

           if(count == 100){ // printing each 100th term

               System.out.println(piValue);

               count = 0;

           }

       }

   }

}
