[Intellij IDEA] How to override a class method, having its instance?

Question

Java

It seems that I formulated it correctly, do not hit with slippers =)
I need to override the method in the class. There are a lot of methods, it’s difficult to do with pens (.
Here is an example of a class:

public class Example extends AbstractExample {

    private AbstractExample example;

    public Example(AbstractExample example) {
        this.example = example;
    }

    void myMethod() {
        int i = 1 + 1;
    }

    @Override
    void doSomething() {
        example.doSomething();
    }

    @Override
    void doSomethingWith(Object object) {
        example.doSomethingWith(object);
    }
}
