sorry for not posting a final post, i found a quick fix to find my answer, here if my final code, thanks for all the help, everyone!

package random;
public class random20 {
public static void main(String[] args) {

        double bot = 1;
        double pi = 4;
        double piequals = top/bot;

        while(plusminus == 0 || plusminus == 1){
        	if (plusminus == 0){
                piequals = top /(bot+(count*2));
                pi = pi - piequals;
                plusminus = plusminus + 1;
                if (flag != true){
