Add an Override after the object is created

Question

I'm using MVC in my project.

I want to separate the creation of the object from the Override.

How can I do it?

table = new JTable() {
        @Override
        public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
            Component component = super.prepareRenderer(renderer, row, column);
            int rendererWidth = component.getPreferredSize().width;
            TableColumn tableColumn = getColumnModel().getColumn(column);
            tableColumn.setPreferredWidth(
                    Math.max(rendererWidth + getIntercellSpacing().width, tableColumn.getPreferredWidth()));
            return component;
        }
    };

You may look into Decorator pattern, which allows adding/changing the functionality dynamically to existing objects. See: [Decorator Pattern Design](https://stackoverflow.com/questions/37521842/decorator-pattern-design) — Nowhere Man, Feb 14 '21 at 09:37
Why do you wish to do this? @Override has no overhead; it's just there to give a compiler error if the specified method isn't overriding a superclass method. — NomadMaker, Feb 14 '21 at 10:01

Follow these steps:

Create a class which will extend JTable and override the method.

Create the instance like this:

JTable table = new ClassWhichExtendsJTable();
