java, extending class with the constructor of main class has parameter

Question

hei. the language is java. i want to extend this class which the constructor has parameters.

this is the main class

public class CAnimatedSprite {
     public CAnimatedSprite(String pFn, int pWidth, int pHeight) {
     }
}

this is the child class

public class CMainCharacter extends CAnimatedSprite {

    //public void CMainCharacter:CAnimatedSprite(String pFn, int pWidth, int pHeight) {
    //}
}

how do i write the correct syntax? and the error is "constructor cannot be applied to given types"

Answer 1

public class CMainCharacter extends CAnimatedSprite {

    public CMainCharacter() {
        super("your pFn value here", 0, 0);
        //do whatever you want to do in your constructor here
    }

    public CMainCharacter(String pFn, int pWidth, int pHeight) {
        super(pFn, pWidth, pHeight);
        //do whatever you want to do in your constructor here
    }

}

You can define any arguments you need for your constructor, you only need to have the super() constructor call as the first line of your own constructor.

Answer 2

The first statement of your constructor must be a call to superclass constructor. The syntax is:

super(pFn, pWidth, pHeight);

It is up to you to decide, whether you want constructor of your class to have same parameters and just pass them to superclass constructor:

public CMainCharacter(String pFn, int pWidth, int pHeight) {
    super(pFn, pWidth, pHeight);
}

or pass something else, like:

public CMainCharacter() {
    super("", 7, 11);
}

And don't specify return type for constructors. It's illegal.

Answer 3

public class CAnimatedSprite {
     public CAnimatedSprite(String pFn, int pWidth, int pHeight) {
     }
}


public class CMainCharacter extends CAnimatedSprite {

    // If you want your second constructor to have the same args
    public CMainCharacter(String pFn, int pWidth, int pHeight) {
        super(pFn, pWidth, pHeight);
    }
}
