Question

编写方法，求如下数值：1+1/3+ … + … +1/(2n-1)； 请问这个用JAVA该怎么做呢

Answer 1

class Count {
public double count(int n) {
double sum = 0;
for (int i = 1; i <= n; i++) {
double temp = (double) 1 / (2 * i - 1);
sum = sum + temp;
}
return sum;
}

public static void main(String[] args) {
Count c = new Count();
System.out.println("sum=" + c.count(100));
}
}
public static void main(String[] args){
Count c = new Count();
System.out.println("sum="+c.count(100));
}
}
