I have an error like this when I call one function inside another in Java.

Exception in thread "main" java.lang.Error: Unresolved compilation problem: The local variable n may not have been initialized

Here is my code:

public class SecondPart {
public static double Factr(double n){
    int i,fact=1;
    for(i=1;i<=n;i++){      
    return fact=fact*i;
    }
}       

public static double ArcSinh(double x){
    double n;

        return Factr(n);

}
public static void main(String[] args){
    System.out.print(ArcSinh(6.0));

    }

 }

Do what the error message suggests that you do -- initialize the offending variable. The error message will tell you which one it is -- initialize it to a default value when you declare it. And never try to run code that doesn't compile (as you're currently doing). – Hovercraft Full Of Eels Mar 07 '17 at 17:59
what is n in your method `public static double ArcSinh(double x)` – BeginnersSake Mar 07 '17 at 18:00
change to return Factr(x); – Nick Ziebert Mar 07 '17 at 18:00
public static double ArcSinh(double x){ // double n; delete this line return Factr(x); // pass x to Factr method } – Jayanand Raghuwanshi Mar 07 '17 at 18:01

Ah, the other thing wrong is your factor method. should be this: public static double Factr(double n){ int i,fact=1; for(i=1;i<=n;i++){ fact=fact*i; } return factor; } Do the first thing I said to did too. My output is 720.0 – Nick Ziebert Mar 07 '17 at 23:15
