Getting rid of deprecation

gracehopper

i've been asked to remove the deprecated methods from one of our projects (written in java). I have a query: It says to replace show() and hide() methods with setVisible(true) or setVisible(false). But if hide or show are method declarations in one file, it doesnt let me have 2 setVisible methods in the one java class. Does anyone know how i'd set these methods up so thet dont give me any warnings?

public void show() //have to replace this with setVisible
{
super.setVisible(true);
}

public void hide() // Have to also replace this with setVisible
{
setVisible(false);
}
}

There's already a setVisible(boolean flag) method in the super class? Then you don't need to do anything other than remove show() and hide() from your implementation.

PS: If you were to add an option for setVisible(true) or setVisible(false) into your class, then you don't put that in verbatim, you put in setVisible(boolean flag) Otherwise trying to put in a method that accepted something like a decimal value could get very messy

why would you want 2 setVisible() in one class?
public void setVisible(boolean b) {
if (b==true) {
// stuff
} else {
//stuff
}
}

If there is a setVisible() in a superclass you may in fact need to override it in any subclass, depending on what the subclass does eg
Superclass -> drawHead, superclass.setVisible(false) {//remove head}
Subvclass -> drawHeadAndShoulders subclass.setVisible(false) {//super.setVisible(false); this.removeShoulders()}


apologies if this doesn't make any sense
