    Default How to add the numbers in the following series?

    class series {
    	public static void main(String args[]){
    		int numerator, denominator;
     
    		numerator = 1;
    		denominator = 1;
     
    		System.out.print(numerator);
     
    		for(int counter=0;counter<=198;counter++){
    			denominator+=1;
    			if(denominator % 2 == 0){
    				System.out.print(" - ");
    			}else{
    				System.out.print(" + ");
    			}
    			System.out.print(numerator+"/"+denominator+" ");
    		}
     
     
    	}
    }
    The series in the program is 1 - 1/2 + 1/3 - 1/4 + 1/5 - 1/6... -1/200, how would you get the sum of the numbers?

    how would you get the sum of the numbers?
    Use a loop and add the individual terms to a variable.
