Unreported exception java.io.IOException when compiling Java code

Question

I am experiencing a problem with this code:

public class gravityv1 {
    public static double[] calculategravity(double[] mass, int[] diameter) {
        double[         


        

Answer 1

You need a try-catch block in your main method around all methods that throw an IOException:

try {
    printFile(gravity);
} catch (IOException ex) {
    // handle exception here
}

Include all methods that have throws IOException after the signature.
