//fix the class
class Pro extends Standard{

protected void useEffects() {

System.out.println("Changing Resolution");
}
}

public class Main {
public static void main(String[] args) {
Standard standard1 = new Standard();
Pro pro1 = new Pro();

//standard version

Please help me

Answer 1

I fixed it on my own.
Just need to change public to protected.

Here is my code 👇

class Standard {
protected void draw() {
System.out.println("Drawing");
}

// this should be changed
protected void write() {
System.out.println("Writing");
}

}

class Pro extends Standard{

protected void useEffects() {
System.out.println("Using Effects");
}

protected void changeResolution() {
System.out.println("Changing Resolution");
}
}

public class Main {
public static void main(String[] args) {
Standard standard1 = new Standard();
Pro pro1 = new Pro();

standard1.draw();
standard1.write();

pro1.draw();
pro1.write();
pro1.useEffects();
pro1.changeResolution();
}
}

Answer 2

That write() method in Standard class is private access so you can't access this from outside that class.
pro1.write() ; raise error....
standard.write(); also wrong..

class Standard {
public void draw() {
System.out.println("Drawing");
}

public void write() {
System.out.println("Writing");
}
}
//fix the class
class Pro extends Standard {

protected void useEffects() {
System.out.println("Using Effects");
}

protected void changeResolution() {
System.out.println("Changing Resolution");
}
}

public class Main {
public static void main(String[] args) {
Standard standard1 = new Standard();
Pro pro1 = new Pro();

//standard version
standard1.draw();
standard1.write();

//Pro version
pro1.draw();
pro1.write();
pro1.useEffects();
pro1.changeResolution();
}
}

Make your private life public
