Question

I currently have a Java program with a functioning Java class. I’ve created instances of that class manipulated them and printed them without any issues, however when I try to extend the class from the main method I get a symbol not found error.

public class Project3 extends StringInstrument{

The main class is Project3.java and the other class is StringInstrument.java so I’m not sure why netbeans knows where the StringInstrument.java file is to create and manipulate instances within it, but it cant find it to ‘extend’ it?

Answer 1

My guess is you need to find the package where StringInstrument.java is.
And import it.

import stringInstrumentPackage.StringInstrument;
