I have this problem, been stuck for hours now.

This method is getting out of bounds exception when i try to print it. Im using the input variables from the method posted below this. Thanks!

public static double [] calcLine(double x, double k, double m){
    double tx = 1;
    double[] list = new double[(int) x]; 
    for(double i =1; i <= 5; i++){

        list[(int) i]+= calcPoint(tx,k,m);
        tx++;
    }

        return list;

}

This is the calcPoint method i use;

public static double calcPoint(double x,double k, double m){

    double calcPointInput = k*x+m;
    return calcPointInput;
}

Cheers L

`for(double i =1; i <= 5; i++)` ... hmmm ... `list[(int) i]`. Look at this again. – Tunaki Mar 23 '16 at 11:37
Hint : When you have array size of `n` , then the array indexes start from `0` to `n-1`. There is no index `n` in it. – Keerthivasan Mar 23 '16 at 11:50
@Keerthivasan, thank you for the comment. How do i fix it? – forTheLoveOfJava Mar 23 '16 at 12:13
@Tunaki, thanks for making me aware of the duplicate question. I read it. But im still not able no solve the exception. Thanks! – forTheLoveOfJava Mar 23 '16 at 12:15
Change to `for(int i =0; i < list.length; i++){list[i]+= calcPoint(tx,k,m);}` – Keerthivasan Mar 23 '16 at 12:51
@Keerthivasan thanks! I sloved it like this `public static double[] calcLine(double x, double k, double m){ double tx = 0; double[] list = new double[10]; for(int i =0; i <= x; i++){ list[i]+= calcPoint(tx,k,m); tx++; } return list; }` – forTheLoveOfJava Mar 24 '16 at 11:59
